Hi. Yes, I am taking small amounts of vitamin B12 dissolvable tablets. I did try taking clonazepam .75 mg per day for a month, and it didn't seem to do anything ,although it has worked for many people.It has a high success rating for burning mouth syndrome relief. My E.N.T. has also recommended taking Gabapentin, but I have the same fear as you, and worry about how it could change me as a person. I'm also exploring the idea of Gaba butyric acid, or what they call Gaba. Gaba is naturally made, and it exists in the brain, but if you have a low amounts of Gaba it can cause burning mouth syndrome. Hope that helps. Let me know if you have any success, and what you're trying. Thanks Stu.
