I recently quit taking Cymbalta about a month ago and am just now getting over the horrible withdrawals. I am a 19 year old female and have been taking this drug since I was 17 along with Seroquel which I stopped about 2 months ago. Since stopping I have gained 20 pounds in a month. I have not had any diet changes and am very confused because I never gained any weight during use of either drug and actually had a terribly hard time gaining any weight at all. Was 110lbs now I weigh 132lbs. Anyone else experience this?
