I've been on 300 mg Wellbutrin for about 3 months, up from 150 mg
which I was on for maybe 2 months.
effect- absolutely NO sex drive!
Most painful side effect- extremely constipated... I eat lots of fruit, drink lots of water, and take stool softeners but to no avail. I'm still constipated, it just hurts slightly less now.
I haven't noticed any major weight gain or loss, although I think it increased my appetite. I'm eating more...but not gaining weight.
