I don't know anyone who has! That's why I really appreciate this website.
(In fact, my sister was on Cymbalta a few years ago, and managed to taper off over a few weeks. She just had a couple effects...brain zaps, dizziness...then she was fine.)
Most people that I talk to are stunned that this could even happen. Sometimes it's hard that no one around me has a clue what this feels like. I mean, I wouldn't want them to have gone through this...it's just hard when you feel alone in this. So again, this website is much appreciated!
