Hey Vitruvian!!!
Ok so I stopped taking them and my sleep went back to normal...so I had to work on a paper the other day and took two AM to keep me going all day long and then I slept just fine that night (no PM though)....I am not sure what was going on but I tried it again last night and everything was fine and my sleep was good.
Should I try just taking PM during the day for a few days and see how I feel with that?
