I've been on Wellbutrin. Didn't have any side effects. I was on Zoloft and built up an immunity to it. I was also on Effexor and those side effects were awful!! If I forgot to take it (which I do now and again), I'd suffer from vertigo. I hated Effexor. That's when he put me on Paxil. I've been on it ever since and have been very happy with it.

I'd call your doctor. It sounds like you're having an allergic reaction from it.
