I. I was on fluoxetine 20 mg for 6 1/2 years. It helped with my moods, but, I completely lost my libido and gained weight. My dr and myself decided Bupropion hcl 75 mg may be a good choice for me. My question... I take this in the morning and find my self in the worst mood ever, incredibly testy, short fused and quick to anger! This is all new for me. This isn't why I started taking fluoxetine years ago, I took it because of the sudden death of my mother and just stayed on it. I have never been someone that has a temper or short fused! It's like I just have a sense of rage! Will this pass and if I take it at night will it be better? Thank you! Please help
