Amitriptyline
"I have been taking amitriptyline on and off for over three years after a serious road accident, where my pelvis was crushed and I suffered major nerve damage. It really really works, but I am trying to get off it permanently because of the side effects. It helps with pain and sleep, which are my two biggest complaints, but the side effects of constipation, dry mouth and a weight gain of 50 pounds (from 120 to 170) are really quite terrible, especially when taken in connection with other side effect causing drugs. I would be very careful about taking this drug. It's very important to weigh the costs vs benefits. Since I was a trauma patient, I didn't have much choice in the matter and I am still living with the consequences."
