I have been on Savella for about a year & I have had good results. However, the copay keeps going up & is now $110 per month. My Dr has switched me to Cymbalta & I start taking it tomorrow. I was told to just drop the Savella & replace my next dose with Cymbalta. Has anyone else been through this transition, & if so, how did it work for you? Better or worse? I'm afraid it won't work as well. I don't want to go back to hurting & having the brain fog.
