I've been off Cymbalta for four or five years now. When I was withdrawing, I had all the nasty side effects as everyone else did such as brain zaps, vomitting, passing out, night sweats, night terrors etc. I thought I was going to die. It all lasted for a few weeks to a month but the brain zaps, night sweats lasted for about six months and to this day, my nightmares are still around. Has anyone else have this issue? I've been to a sleep doctor but no one can figure it out. I'm not on any medications anymore (after finding out gluten and sugar caused my anxiety and depression). These dreams are so vivid and mostly extremely scary; every night. Prior to Cymbalta, I rarely had dreams like this. I swear this drug messed up my brain.
