major depressive disorde
"I'm male, 54 years old and weigh about 180 LBS. The first time I tried Wellbutrin, it was 150mg twice a day. It was too much for me. Side effects: Jitters, hyperactive, constant bouncing of knee when sitting, clenching teeth, weight loss, tinnitus, insomnia, dull headache in back of head.

I decided to quit Wellbutrin but recently resumed using it. I only take 75mg in the morning (5 AM) then 75mg at 11 AM. They are the "SR" type. I will continue using this dose until my body adjusts and then I may up the dose to 150 twice a day.

For me, starting at 300mg a day was far too much. I believe starting lower, I will be able to remain on this."
