I have what is known as dry mouth. I must sleep ...

How long has this been going on?  If it's a short-term thing, it probably is some type of infection or virus.  If it has been going on for awhile, it could be diet-related.

Are you getting enough fat (and enough good fat) in your diet?  The dryness of your skin, mouth, hair, etc. all depend upon getting adequate dietary fat.

You should indeed adjust your diet. In the meantime, try biotene (http://www.laclede.com/).

I once had this problem, but I found that if I put a Life Saver between my upper teeth (gums) and jaw,(it will stay there) it would increase my saliva. Try it!!

First, make sure your dental health is good...how often do you have your teeth cleaned? plaque buildup aggravates dry mouth..also, you must use the toothpastes and mouthwashes made for dry mouth; Oasis and Biotene are the 2 I use...Oasis usually has coupons, also...Try to drink more water, and watch your caffiene intake, as it will aggravate your dry mouth.....You should also see an opthamologist & get the test for dry eye; the two go hand in hand, unfortunately!!! for that, you need eyedrops probably for the rest of your life...my eye dr. recommended Refresh Liqui-Gel....Hope this helps!!
