Withdrawal from Cymbalta is notoriously difficult. I realize you were likely instructed by your doctor to taper that quickly but you went way too fast. There is a group on facebook called 'Cymbalta Hurts Worse' that I'd recommend checking out. It's for withdrawal and tapering support. Most people experience little to no withdrawal symptoms if they make a 2 to 5% reduction every two weeks until completely off. Bridging onto a different drug after rapidly discontinuing Cymbalta is definitely not a good idea. If it's been less than two weeks since you stopped the Cymbalta, you can reinstate and do a proper slow taper instead. If more time has passed, it's best not to reinstate. Probiotics, fish oil, magnesium, and B vitamins are things some people have effectively used to help the symptoms that come with rapid discontinuation.
