Venlafaxine
"My doctor put me on this medicine for hot flashes and the roller coaster emotions that come along with pre-menopause. 37.5mg. After I took the first dose I started sweating, shaking,  got nauseous and started violently vomiting, along with diarrhea. I had the dry heaves for 4 hours. Very scary. I almost went to the ER. I will not be taking this medicine! I'd rather have the hot flashes!!"
