Well, I've noticed an increase in heavy sweating in the last 5 months as my SFN progressed very rapidly across my entire body. I wake up and change my t-shirt 3-4 times a night as I wake up soaking wet! I am hot, then cold changing often, maybe 10-15 times an hour. I have taken 3600mg of Gaba for a much longer period of time than this issue, so I don't think it has as much to do with it, but maybe it does. My legs from the knees down thru my feet are always very cold, though I'm not in a cold house or anything like that. And our weather here in AZ is not really cold or hot right now.

I only guess that the nerve damage is just sending screwy data to the brain, some nerves tell your brain parts of your body are hot, and some parts are cold. If the Gaba is causing it, I doubt it, but who knows.
