Hi Scoopy,
I take nortriptyline - I started is originally for neck and shoulder pain from a pinched nerve in my neck. It definitely helped with that - I could feel it. I had to get through some initial drowsiness, but I acclimated quickly to it.
I am also certain that it kept my TN from punching through harshly when it began, because I was able to adjust it upwards and see relief to my TN from it, until I eventually maxxed out.
I keep wondering whether it is contributing anything now, though. I just take it along with all the other meds.
Good luck with it - it really does work on nerve pain.
