I do not have this issue. My issue is dry mouth. If you see the answers above, some have had luck with acupuncture or botox injections. For short term relief try to eliminate anything you are eating or chewing containing Xylitol as this is what we use to increase saliva production. Others have had luck using an antacid that decreases stomach acid production like Prilosec. Keep reading through all the responses above for more suggestions.
