I've been taking effexor for almost 2 weeks for GAD, OCD & depression and I really haven't experienced too many bad side effects and some of the ones that were bothering me have almost gone away. But the most fantastic side effect of all is I have no appetite at all. I don't even think about food. It's almost as if my obsession of food is gone. I'm not stressed by eating at all either. It really feels great. I wonder if maybe it's not a side effect but something this drug is supposed to be doing for me. For a number of years food and mealtime has been very stressful for me, so it feels good to not have that stress. As a result I've been able to lose a few lbs these last 2 weeks too.
