Hi there! When I first took Efexor I had pretty bad side effects for the first 2-3 weeks then I started noticing them waning.

I started on 75mg, and noticed the sweating, dry mouth, tiredness, i'd sit on the couch all day and feel zonked. Also nausea and dizzy.

Side effects generally do settle down, see how it goes in another week i'd say.

I've been off Efexor now for 3 months, but they did help me, I just didn't want to live with the side effects that stayed with me - the nightmares, nausea etc.
