I am prescribed 60mg cymbalta at bedtime for cervical disc pain as well as migraine prophylaxis. I lost my insurance in february but I had a bottle of 30mg cymbalta left over from when I first started it. I took 2 30mg capsules at bedtime a few nights ago and woke up vomitting in the middle of the night... is this because 60mg is now too much for me? Should I go back to the 30's for a week and then take 60mg after that? Thank you!
