300 mg. - even went back down to 150, but was still itching and could not sleep.

Going back on Cymbalta - trying a lower dosage - 30 mg. (may go up to 60mg. if needed). Was on 90 mg. before. Feel much better yesterday and today (just took my first Cymbalta).

I'm bummed too. I think the dopamine was causing me to have too much anxiety as well.
