I finished treatment in June, and chewed a lot of gum up through September and started to get a lot more saliva in October. Somedays I feel like I have a normal amount of saliva, then suddenly it's less again. To put it in perspective--my acupuncturist at Dana Farber said he has several patients that awaken hourly each night because their dry mouth is so bad. So I would say if you are not getting up several times a night consider yourself lucky.
