Thanks for using Doctorspring.com for posting your query.
I have gone through your question in detail and I can understand what you are going through.

GabaPentin is not available without prescription and that makes it clear that unless your doctor writes it, you are not going to get it. So coming to the next option as substitute. You have been using gabapentin for two reasons...one the mood stabilizer and the second the neurogenic pain. For mood stabilizer there are plenty of other drugs as well like valproate or lithium or carbamazepine which your doctor wont be afraid to write. More over the third option i.e. carbamazepine is also a good drug to treat the neurogenic pains. So this molecule could be a good drug to substitute Gabapentin. And the best part is unlike Gabapentin it is not habit forming.
I would suggest that you discuss these point with your psychiatrist and get the medicine changed to carbamazepine and get off gabapentin completely. Even if you become habitual to it, the things should stop at some point.
Hope this helps

I feel really sorry for you that the tegretol has not worked for you. But believe me there are plenty of other options for neuropathic pain which you can try for. One option is combining pregabaline and nortriptyline which comes as a combination tablets. That will help you in reducing the dosage of pregabaline. I have personally seen many patients improving on this combination. Other option could be biofeedback based relaxation therapy which is also very effective.
Hope this helps,
