Acupuncture sounds like a good idea. Also, keep in mind that SSRIs are all different. You may have better luck on a different one. Effexor is notorious for its nasty side effects - I should know - I was on it, too. But, it made my IBS disappear completely. Ask your Doc about trying another SSRI. Plus, the sexual side effects can be taken care of by taking wellbutrin as well.
