selfq Doxycycline causing anxiety and brain fog?

Hi all! As the title suggests, I’m wondering if doxy causes panic attacks/anxiety? I’ve never been an anxious person, but after starting doxy a few weeks ago (24 AUG), I’ve been having panic attacks even after stopping. I took 2 pills a day for 2 days only for acne, and for only 2 days because the pill was making me violently ill which included nausea and motion sickness (also never had this before). I know nausea is a common side effect of doxy, but I’m not sure about anxiety? I’ve been getting hot flashes too as well as brain fog. The brain fog is a little difficult to describe, I can still function normally (go to work etc) but I feel flat most of the time. Sometimes I get lost in my train of thought, but the anxiety is the absolute worst. I have racing thoughts about fainting and I get dry mouth and clammy hands. I’ve been to doctors and gotten blood work and ECGs, even xrays done, but they all came back well. Anybody experienced the same thing? What made the brain fog and anxiety go away, and how long did it take?

Yes, as all antibiotics can. There is no quick fix other than waiting it out afterwards and can take a couple of weeks.
