i'm making the switch to cymbalta from effexor... i think it had just run it's course and wasn't working for me any more. over the past four yrs. i have gained a lot of weight (due to depression, trying out a few unsuccessful meds, etc) and i've heard that cymbalta can help you lose weight (or at least you won't gain with it)... has anyone found this to be true? i haven't had any major side effects since making the transition, which is nice! also, does this med tend to increase your energy level because that's something i definitely need. i was taking 300 mg effexor and felt pretty drained most the time. i know that everyone experiences different effects with meds but any feedback would be appreciated.
