Cymbalta Side Effects: Appetite Loss and Insomnia

I would talk with your Dr. about your concerns

Talk to your Dr before you do anything! Sometimes it takes a little bit of time to get in your system. Eat small meals, several times a day and you can take Melatonin for sleep.

I would still wean from it, the only time you can just stop I would think would be if you on it less than a week.
