I intentionally join this forum to share my experience . I am on Gabapentin for over a year going from 100 mg a day going up to 700 mg . Each time with a 200 mg raise, my right leg neuropathy pain subsides for a short time and come back with a vengeance.
Somehow, I stumbled on a supplement called Alpha Lipoic Acid . After further research, with nothing to lose , I tried using it, taking 2 600 mg capsules a day. It's only less than $25 for 4 months supply ( Amazon , Ebay or many other supplement sites ) . It's almost 2 months now so far, I notice my leg pain is much better. Even I still feel the pain during the day and more noticeable at night, but it is fairly mild and not having to take Motrin or Tylenol at bedtime. I even test to lower my Gabapentin dose to 600 mg . It is still early to tell, but not having to go back to the doctor to increase my dosage is a very good sign and give me hope for better result and may be able to keep lowering my Gabapentin dosage.
I hope this help
