Think about Kitt's question as where you go from here is a little different if your neuropathy is hereditary.
As for the Gabapentin, you don't really tell us whether you are suffering from the burning and electrical buzzes that Gabapentin may help with. It doesn't always help, but since it is a fairly safe medication it is routinely the first thing tried. For myself, and I have hereditary neuropathy, the Gabapentin does keep the burning and zaps under control. The visual blurring has not gone away as a side effect, but the fatigue and balance issues did, so your side effects might not persist. Mainly you have to determine for yourself if the medication is worth the side effects. You are not really at a therapeutic dose yet - 1800-2400mg.
The more you tell us about yourself the more help you will get. How old are you? Has the doctor suggested that the cause is alcoholic? Are your B-12 numbers low? Most nerve patients should supplement B-12, but low number alone can cause reversible neuropathy. What tests gave been done?
Lots of helpful and knowledgeable people here, don't be afraid to ask specific questions. Your plans sound sensible, but tell us more about where you are with this. Working? Hobbies? How has this affected your life?
