That was the sexual side effect I had. No desire for sex and it was harder to have an orgasm.My body wasnt working the way it has. But I dont have that anymore since I went down to 10 and am taking wellbutrin 150 (which I heard ups your desire for sex).

I was tired on lex and then took it at night instead. Then i couldnt sleep and went back on it during the day and it doesnt make me dizzy and sleepy because my body is used to it now. But I had that drowsy thing from lex for a looooong time. It went away now.
