Amitriptyline
"I was prescribed Amitriptyline for herniated disc and nerve pain.  I took 10mg every night for over a year.  Having had regular physio I made good progress and decided to come off them to see if I still needed them.  Also my teeth were suffering from constant dry mouth and my hair was falling out at an alarming rate.  Both symptoms stopped within 2 weeks of coming off them however 3 weeks in the nerve pain has returned.  I can't decide if going back on them is worth losing my teeth and hair for !  Also due to its sleep inducing properties it can for some be very addictive, I certainly have as good a quality of sleep as I did."
