In January I was prescribed Viibryd on top of Wellbutrin I was already taken & now here it is May & have gone from 150 to 190. All information I read regarding Viibryd tells me it doesn't cause weight gain but something has got to be going on. I've never gained weight like this even when my thyroid was all messed up before medication. It's just depressing trying to get into clothing just to go to work that you could wear a week ago & now can't. And available information would be greatly appreciated.
