The reason I was put on Wellbutrin was to combat the effects the Effexor was having on my sex life. My orginal problem was that I could'nt orgasim after the first few weeks on it. The doc wellbutrin will combat this side effect. I am going to see him later on this week, ill ask him to up the wellbutrin to 300mgs and stay on the efffexor or if it would be better to just drop it all together.
