I am only saying that the nortriptyline may be more effective than the gabapentin. (new meta analysis of gabapentin found it only effective in about 30% of cases).
For that reason it is worth trying it. If it works well, you could consider tapering off gabapentin to see which is doing more for you. People all vary in responses to drugs, so one has to try them to see.

Usually low doses of this drug work for PN.
