I take nortriptyline and find it to be moderately helpful. I did not do well on neurontin, it helped but killed my mood. The nortriptyline does help with sleep and does help with my stinging pain. If I could tolerate a higher dose it probably would work better but I had to decrease due to dizziness. I started on 25mg before bed but went down from there. It came out in a pain study for neuropathic pain the people have better relief from a lower dose of both an opioid and another med like TCAs together than either med alone.
I hope you find relief soon. Sending Healing Love, Littlepaw
