I just started taking prep last Friday and have taken a pill everyday since. I know the time window for on demand prep is super strict but how is the time window for daily prep? I don't take it at the exact same time, but I take my daily pill from between 11am - 12. So I take the pill within that same one hour period everyday. I'm just paranoid because I just started it and I want to take it correctly. Do I have to take it at the exact same time everyday or is it okay to be within an hour window like this. I just want to make sure I'm protected. I researched on some websites that you're fine within 12 hours but I would never wait that long anyway.
