I m a 25 year old woman who at night sometimes has extreme hunger pains (despite just eating a snack,) and hot flashes sometimes to the point of sweating. Usually, when this happens, I feel like I have to both vomit and have a bowel movement at the same time. I go back and forth to the bathroom, but only gas comes out. Eventually, I normally am able to have a lot of bowel movement come out and then I feel back to normal. I m on venlafaxine for depression and for a over the past few years I ve taken other medication for depression as well. Could my symptoms be related to my medication?
