Heres what I found out about either
Diovan,
Xanax,
Lexapro, or Vitoryn.
One of them does make you gain wait, but only if you let it.
For example, if I eat sensibly (say 2 chicken breasts *minus the skin( and soem vegetables) then I lose weight, on the other hand I was as a friends out last night and ordered up 2 pizzas, and dang if I didnt let myself eat a whole pizza to myself. I let myself do it because I never got that stuffed feeling from one of these drugs that Im taking. (Normallly before I was prescribed all these drugs, 3 pieces of pizza and I was stuffed to the gills and couldnt take another bite) So, you must show self control when eating if it's lexapro that your gaining weight on because if it is the Lexapro it's like blocking your "fullness" body meter and allowing you to gorge yourself.
Thats my two cents on it.
