I started Cymbalta a month ago and after a week began to have trouble sleeping, awake for hours in the middle of the night. Next I had burning pain on the roof of my mouth which turned out to be small ulcers. These were thought to be stress related and my doctor suggested I take Lorazepam for five days to get some rest. I am feeling more and more wired up during the day and now have small white blisters on the insides of my cheeks, on the roof of my mouth and all along the inside of my lower lip. So now I can't sleep well or eat well. So I want to come off.....but it has only been one month. Any thoughts on the taper? I have read 10% at a time, for one month but read all sorts of others also. My doctor suggested the usual, one day on, one day off, which sounds like it does not go well. I have also read that you could take Prozac alongside it for two weeks and then come off the Cymbalta and then have a faster weaning off the Prozac.
