I take the generic for Wellbutrin(bupropion) and it is so far the only anti-depressant I have taken that both felt like it helped and didn't have any noticeable side effects. I was taking 150mg a day for quite a while but my doctor just bumped it up to 200mg daily. I also take the generic for Buspar(buspirone) 10mg twice/day. The combination seems to work well for me.
I am also in the process of cutting soda from my diet due to the excessive calories and sugar but feel the caffeine is beneficial so I am taking a 200mg caffeine pill in the morning as well.
