Amitriptyline
"I've been taking 10mg Endep for 2 weeks for bladder pain. I may have a mild case of interstitial cystitis but I haven'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'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."
