Has anyone had a problem with increased anxiety from taking bupropion? Has anyone had a problem with ringing in the ears (tinnitus) while taking wellbutrin? I have taken generic wellbutrin for years. Just recently quit taking it because of unbearable side effects. Been off of it for 2 weeks. No more ringing in ears, sleeping better all night long, no more joint pain, no more anxiety attacks. Has anyone else experienced these adverse side effects?
