Accupuncture has been shown to work from what I've read. Personally my mouth is a barren waste due to the facial paralysis not allowing my lips to close fully, ever. It comes with it's own bag of issues but mostly just inconvenient.

I workout hard and have to keep sugarfree gum and water close at all times especially if I'm trying to eat solid foods. It's doeable though, I don't think about it much anymore.

Good luck, keep your chin up!
