pre-exposure prophylaxis
"I'm been taking Pre-exposure prophylaxis for HIV (PREP) now for over 3 years. It's kept me HIV negative, thankfully.  However, the longer I'm on it the more issues I have with sleep and irritability...  I also feel like I'm not very enthusiastic as I was before taking PREP.  This can all be tied to the sleep problems that I feel are a side affect of TRUVADA.  So I'm not completely free of side affects. But I am glad that their is a pill we gay men can take to protect us from HIV."
