I used to take Venlafaxine myself – Stopped in Nov 2010 or so. It *always* made my stomach feel funny. I found myself nauseous almost every morning from it. Usually i’d eat something with it to calm the effect.
I stopped taking Venlafaxine though. While I liked the benefits, the downsides were bad for me. It gave me frequent headaches, lots of gas – and I mean ENORMOUS amounts of gas, made me VERY groggy in the morning until i had coffee, among a number of other things… That, coupled with candida… not a good mix! I stayed on it for about 5 months.
Hope that helps?
