My doctor prescribed venlafaxine 37.5mg bid today for anxiety. I took the first pill today after dinner and within about an hour and a half my stomach started to hurt. I had intense nausea and knew I was going to throw up. Within a few minutes I was vomiting non stop and then had diarrhea.

I do not feel like myself. I feel very shaky and just strange. Could this be from the venlafaxine? I am hesitant from taking them ever again.
