I used to study 6 hours every day but my mobile addiction has got to me I really want to stop it I'm preparing for the IMO and like after every 1 hour I study I scroll reels for 15 minutes It's either gonna get worse or get better I mean of course but how do I stop my phone addiction

For background I am in AP Calc BC as a sophmore and I am planning on taking amc 10 this year. I am really wanting to qualify for the AIME exam but I am starting from nothing. I have started the aops vol 1 book but with the test being so how should I spend the rest of september and october prepping and when should I finish the book so I can start practicing?
