I take 3600 mg daily @ 900mg increments 4 x's a day. Yes it helps with the burning pain, but I didn't realize it helped until I was on a high enough dose of narcotics that I could tell it helped. At one time I was on 4800 mgs a day. I don't seem to be suffering from any type side effects, but then I have been on this med since 2003. RSD is in both of my feet.
