Advice & Tips: the benefits far outweigh the downside for me. It can be different for other folks, the stuff was poisonous to a friend, he developed pancreatitis and nearly died. I trust it's effectiveness though, i've not experienced mutations or resistance, even when i lapsed for a month on this as well as my epzicom, again resulting in a miserable rash.
Cost: < $25 monthly
Side effects: vivid dreams, night sweats
