57 year old woman with 8 months of burning mouth. After trying everything, Alpha Lipoic Acid supplements really worked. On a pain scale of 1 to 10 (10 being suicidal) I am now a 2. Very livable. I take 400mg capsules 3X daily. I'm also noticing that MSG is causing flair ups. I'm going to avoid anything with MSG in it, which unfortunately is about everything. I want to hear back from you after you try it for about a week or two. I noticed a difference in just a few days.
