Pyro is right, it's a side effect. Talk to your doctor about trying different meds. I take Cymbalta and get along really good. Still have emotions, except can't get really sad. No change in the sex drive. Don't just stop taking them, you need to be weaned off of them or you could go into a deep depression. Also, if you are taking them because you are bi-polar, you could go into a rant that would be destructive or hurtful to others. Just talk to your doctor about trying other meds, first.
