Amitriptyline
"I am not much of a prescriptions type person but I tried this medicine and at 50mg each night. WOW! I am feeling normal for the first time in 20 years. My insane thirst and aches are gone (most days). 

The side effects are severe constipation and all my old injuries are flaring up. 

I don't mind though. 

I'd rather not have bowel movements and a bad ankle than Irritable Bowel Syndrome. "
