This is probably a fundamental question. Let's say you plan to be with someone over a weekend and you know that each weekend day will contain activity that you would like to be protected by 2-1-1 PrEP. So from reading the thread, if you consider just one of the days you would take 2 pills optimally 24 hours before and then 1 pill each of the days after. But how about that middle day. I have a feeling you would not take 2 pills 24 hours before that. Does the first two pill dose cover that (followed by one pill per day after that)? Or is there some other set up you would recommend. Thanks.
