Amitriptyline
"I have been in chronic pain for 11 years, worsening in the last year.  Finally a pain management doctor prescribed me 25mg of amitriptyline and it worked overnight. Magically the next day my pain was down to a completely manageable level. I have my life back thanks to this medicine.  Dizziness the first day or two, dry-mouth only if I stay up long after I've taken the medicine.  Don't hesitate to take this medicine if you have nerve pain, it is a miracle."
