I Am Currently Taking Cymbalta 60 Mg Once A Day

I am currently taking cymbalta 60 mg once a day in the morning for neuropathy, and it just so happened that I have depression (self diagnosed) I have gained 40 lbs since I started taking this. I am not on any other prescription mnedications. My neuropathy is alcohol related. I am not drinking any more. I have tried a lot of things to lose weight but I can’t. My weight gain is in my mid section , neck and arms. I’m 57 and have never weighed this much except when I was pregnant . What can I do?
