"i&#039;ve been taking 10mg endep for 2 weeks for bladder pain. i may have a mild case of interstitial cystitis but i haven&#039;t been officially diagnosed yet. i have found it has worked really well with the pain. i went from being in pain all the time to only a couple of times and it&#039;s been manageable. i have dry mouth and an increased appetite from endep but the worst side effect is constant drowsiness and a general feeling of being drugged up."
