Shame that Clonazepam can be habit forming. Because I can tell you, 2 hours later, it has helped the burning mouth for sure. She doesn't want me to take it beyond taking it on days where I feel the mouth pain is bad. Some days I do actually have relief from it.
My doctor asked how I got so knowledgeable about different medications, so I name dropped NeuroTalk.

And mentioned I post on a burning mouth forum as well with many in situations like mine, no known cause, just burning awful mouth pain.
She said, "Isn't the Internet wonderful?". Got that right doc!
