peripheral neuropathy
"Started with 300mg at night with no significant improvement in symptoms. Second week 300mg night, 300mg day.  The daytime dose knocked me out, feeling drowsy, dizzy and fuzzy thinking. Cut back the daytime dose to approximately 150mg - same results.  On top of that the burning and tingling got worse. Doc had me stop all medicines. Glad that many get wonderful results, but not me. (By the way I'm not diabetic, no thyroid problems and no alcohol use)."
