Hello,
I, too, had burning mouth syndrome a few years back (going through "the change")
and did my own research.
The one drug recommended for it, is klonopin. The generic version is "clonazepam."
I've been on it, off & on..
It's a long-acting 'form' of xanax....a benzodiazipine. (sp?)
Anyway, I think a small amount, morning and night, might help.
Do a little research online & put in the words, "burning mouth syndrome and klonopin" and you'll see what I mean. It's the drug of choice for that particular problem.
I'm taking it for entirely different reasons now, but it's wonderful for that weird burning thing, some women seem to experience.
Hope I helped.
Let me know how you're doing.
S.
