I don't know if my response is of any help as I've been on this med for only 2 weeks now, (and it being my first antidepressant ever prescribed to me).
I'm on Wellbutrin 120mg. 2x/day

I have tremors, too.

Anyway, side effects I've been feeling are a few, (not sure if they're normal, or not).
Clenching teeth.
Head feels like in a vise.
Ringing in ears.
Sweaty palms.
Pressure in chest.
Difference in breathing. Briefly holds breath, releases...repeats.
Headache on left temple.

All these symptoms fade then reappear all throughout the day. On and off, type of thing.

I have no idea what positive is supposed to come out of taking antidepressants. Hmm.

Sorry if this wasn't of any help...
