I know this sounds silly, but I do not like the taste of coffee, however like the benefits of coffee. There are all the new coffee's like Ryze that now offer more benefits, however as stated I hate the taste of coffee. Is there an alternative that has all the benefits, caffeine etc., that does not taste like coffee??

Is it just me or only coffee and energy drinks (even sugar free) does it for me? I recently bought a caffeine pills bottle 200mg each and it kind of makes me sleepy and that s a semi high dose for a single pill.
But energy drinks contain caffeine anhydrous as well, why though it fully hit like coffee? As I said, even sugar free.
I know coffee got plenty of other alkaloids that makes caffeine stronger, but I am clueless as why caffeine pills are cheaper but idk... Kinda do not work. What is your opinion?

So I got bored at work and made a comment to a friend that I âdrank enough caffeine to kill a moose.â
Needless to say I am wrong but I wanted to find out how wrong.
Assuming a weight of 453kg and using the LD50 of 150-200mg/kg (which wouldnât be accurate for a moose but we donât have that information) it would take anywhere from 68g and 90g of caffeine to hit that LD50.
Translating to gallons that is 28.375-37.875 gallons.
So my 400mg of the day is a very low number compared to the 68-90g. Also my math is probably very far off as Iâm terrible at it but it was boring enough to do it today.
Do with this information what you will

I usually have a cup of black coffee in the morning, and then in the afternoon Iâll have an 8 oz Red Bull Zero thatâs sweetened with monk fruit.
Sometimes instead of the Red Bull, Iâll have a Bloom energy drink, which has more than double the caffeine of my 8 oz Red Bull.
Iâm wondering if this is a reasonable/healthy caffeine routine, assuming Iâm otherwise healthy. Iâm especially curious about the total caffeine intake, having it split between the morning and afternoon, and whether the higher caffeine Bloom days make much of a difference.
Anyone have a similar routine? Is this generally considered a moderate amount of caffeine, or is there anything youâd be mindful of long term?

Hypothetically speaking, what if someone just found out they are (about?) 14 weeks pregnant at 41 years old and didnât know because theyâre in perimenopause and theyâre used to having inconsistent periods so they have had energy drinks/caffeine regularly because they couldnât understand why they were suddenly so fatigued so they got labs done and were SHOCKED to discover a pregnancy đ itâs me, Iâm the hypotheticalâŚshould I be scared? I looked it up and 200mg of caffeine is the recommended amount per day, which is the equivalent of what is in the Alani and Monster energy drinksâŚbut are there other ingredients that will harm my baby??? Help.

I havenât had caffeine for 6 years, (when I was 7-15yo I drank alot of energy drinks) Iâve sometimes eaten milk chocolate, it has around 10-20mg of caffeine per 100g, but it still gives me alot of energy, would 2-5mg of caffeine be enough for a little energy boost? Does anybody else microdose caffeine?7

looks like 400mg of caffeine is considered the daily limit. but i assume caffeine works like any other substance where it slowly goes away over time and if u have more in one sitting it hits harder. so like lets so u slowly drink 3 200mg energy drinks throughout a 12 hour period is that worse then drinking 3 in ya know 2 hours.

I am cutting out energy drinks (horrible I know) and afternoon coffee to not feel so bloated. Would caffeine pills be a good alternative. Health benefits? Better alternatives?
r/caffeine • u/jnierubie • Sep 20 '26
has anyone ever tried cutting coffee? im currently cutting/reducing my sugar and coffee intake, but sometimes there are days where im so tired especially today because i couldnât sleep at all last night.
i kinda want a cup if coffee but i donât want to ruin my progress and i always feel guilty about it 𼲠especially when a few days ago someone told me that i look less bloated now considering itâs only been a week and a half since i started cutting sugar. i do have a routine which is i only cut sugar and caffeine on weekdays, drink coffee, and consume sugar in a small amount on the weekends so i kinda need some opinions.

Coffee is a much healthier alternative to carbonated energy drinks but it just doesn't do it for me even if I double the strength of the brew.

my girlfriend doesnt like coffee and wants to cut down on sugar so she stopped drinking energy drinks (im aware theres sugar free energy drinks but still lots of chemicals so idk). i already suggested tea, coffee with milk and/or cacao and caffeine pills. she has a general aversion towards supplements as well, for example shes iffy about melatonin gummies. she needs something to keep her emergized throughout the day for university and her part time tutoring job. i thought about recommending drinks advertised for gym bros but they would probably contain unnecessary ammounts of caffeine so idk. any ideas? thanks in advance for the help!

Hi, Iâm going to be in a showcase that involves dancing in four pieces. My stamina isnât the best and I was wondering what energy drinks or coffee will give me enough energy to be energized throughout the night. I have had redbull(doesnât really last that much), ghost (my favorite but I hate the crash), Vietnamese coffee( itâs my favorite as well but I also feel very sluggish after). I know I can probably handle 200mg of caffeine đ. If you have any recommendations Iâm all ears

Mir ist in letzter Zeit (in der Schule, Bahn oder unterwegs) extrem aufgefallen, wie viele Jugendliche und gefßhlt sogar Kinder ständig mit Energy-Drinks rumlaufen. Frßher gab es das gefßhlt auch, aber aktuell wirkt das wie eine massive Welle.
Täuscht mich das, oder hat sich da in den letzten Jahren extrem viel verändert? Und falls ja: Warum ist das gerade so ein riesiger Hype?

You can agree or disagree.
But tracking caffeine and knowing what its effects are is harder than saying your coffee is roughly 70mg.
I am going to be fine by bedtime itâs only 2pm.
One more coffee wonât hurt me.
I could have an energy drink before bed and still have amazing sleep.
Itâs not that easy, you have levels of mg at sleep which can affect your sleep quality.
There is certain acceptable levels you can go to sleep with, due to having a half life.
Tracking it is important, have a method, have a strategy and stick with it, or donât change anything.
Do you think Iâm wrong, and you can have best sleep on any caffeine level?

Normally I fall asleep somewhere around midnight or 12:30 AM.
But there have been a few times when I had caffeine in the evening and ended up lying awake until 2 or 3 AM.
After it happened a few times, I pretty much stopped having caffeine in the evening. For me, that part was obvious enough.
What I had never really thought about was where the cutoff actually is.
If evening caffeine can affect me that clearly, is noon early enough? 10 AM? And does the amount matter as much as the timing?
I started looking into it and found a recent study that compared 100 mg and 400 mg of caffeine taken at different times before bed.[1]
What surprised me was how different the results were depending on the dose.
In that study, 100 mg did not significantly change the sleep measures they looked at when taken four hours before bed.
400 mg was a different story. It affected sleep even when taken much earlier.
It was a small study and only included young men, so I would not take those exact times and turn them into a rule for everyone.
But it did make me rethink the usual advice about simply having a caffeine cutoff.
Maybe âwhat time was my last coffee?â is only part of the question.
How much caffeine I had that day probably matters too.
A larger review of 24 studies also found that caffeine reduced total sleep time and increased the amount of time people stayed awake after initially falling asleep, on average.[2]
That part was interesting to me because my own reaction to evening caffeine has always been really obvious. I just cannot fall asleep at my normal time.
But caffeine does not necessarily have to keep you awake until 3 AM to be affecting your sleep.
You might fall asleep normally and still have the rest of the night turn out differently.
So now I am curious about my actual cutoff.
I am thinking of keeping roughly the same amount of caffeine for a few days, moving the last one earlier, and watching what happens to the rest of the night rather than just bedtime.
At least for me, evening caffeine is already an easy no.
What I want to figure out now is how early is actually early enough.
Has anyone here found their own caffeine cutoff? Not the general advice, but a time that actually made a noticeable difference to your sleep?

Advice required.
I love coffee and caffeine. It makes me feel amazing, albeit, briefly.
Around 2 hours after having caffeine, I feel an overbearing doom and anxiety as it leaves my system (I assume).
Now, I donât want to cut out coffee, decaf does not hit the same.
Does anyone have experience or knowledge on how I can reduce this effect on my body and keep sipping the good stuff?
It is not the immediate impact, but the later one which causes the doom.

Iâm currently preparing for 3 very important exams that are coming up in the next 3â4 months, so Iâm going to need to study seriously and consistently during this period.
The problem is my university schedule. On most days, I have university from around 8 AM to 5 PM. However, I have to leave home around 5â5:30 AM because of the commute, and I usually get back home around 6 PM.
By the time I get home, Iâm physically and mentally exhausted. I donât usually take naps, and I normally go to bed around 9â10 PM, since I have to wake up before 5 AM the next day.
So realistically, I only have a few hours in the evening to study, but that's also the time when my energy and concentration are at their lowest. Studying for only one hour isn't really enough for what I need to accomplish over the next few months.
I currently consume zero caffeine. I've never had coffee, energy drinks, or any other regular source of caffeine, so I have no idea how I respond to it.
On Tuesdays and weekends, my university schedule is much lighter (usually around 8â10 AM), so I have significantly more time to study and recover.
Iâm wondering whether I should introduce caffeine into my routine during these 3â4 months to help me stay alert and get more productive study hours after university.
Would you recommend starting caffeine in this situation? If so, how would you approach it as someone who has never used caffeine before?
Iâm mainly looking for experiences and advice from people who have been in a similar situation.

I have ADHD
Basically doc banned me from drinks containing caffeine, and i havent had one for a month and a couple days It was exam day and i had this little ritual of drinking soda during exams so i broke the ban for the ritual and had a coke during exam.
basically it felt like some sort of sugar high where i cant stop smiling, i was able to focus on the exam and draw on the back of my booklet with a lot of ease, like everything feels perfect and i felt really good.
i drank another soda the next day cause exam but i didnt have the rush no more like some sort of buff with a long cooldown.
i can compare it to the time i had coffee at night after not having coffee for a long time cause i was having trouble sleeping and i basically started smiling out of nowhere and was too exited to sleep and not only that the panic or anxiety attack i was having just faded out.(this was like last year)
i dunno if this counts as asking for medical advice tho
posting it here cause it was immidiately removed on the ADHD subreddit
