It's been a year since treatments ended and I still have dry mouth. I can produce minimal amounts, but the radiologist told me that the rear glands were probably gone. They work maybe a little but I have had to alter my diet drastically, and actually it's probably a good thing! One interesting side note though, when I had a bout of nausea a few months ago my mouth gushed with saliva, very interesting! It's almost like the glands are dormant, so as was recommended to me, I think accupuncture may help stimulate those puppies.
I find that water is an astringent so I rarely use it. I prefer watered down juice like apple juice because a small amount of sweetness stimulates saliva better. I always have some by the bed and by my side during work cuz at night my throat gets sooo dry and my lips are chapped by morning.
At first I always had water around but after a few months I tapered off because I find that I am forced to make my working glands produce by trying to lubricate naturally. My ENT said the moisture does seem improved. I still need to wash down most bites of food with some rice milk or juice. Water destroys the flavor, so I prefer something more like rice milk (lactose intolerant!) to drink with meals.
With wine I water it down too about 40-50% and it's fine, actually Europeans drink it like that very often. Carbonated drinks are no good cuz my throat tissue is sensitive. I prefer my beer less cold now, Guinness is better cuz it has less bubbles. I drink rarely but my doctor said a little is okay.
As for bread, you shouldn't eat it anyway, since it is all carbs and carbs - sugar and sugar is CANCER FOOD. But IMHO toast is better than fresh oddly enough. Soft bread is a sponge, whereas toast can be washed down easier. Chicken breat meat is also difficult, and salmon isn't fun anymore either. Red meat is fine as long as it is medium rare.
RECOMMENDATION TO ALL:
Read "THE HIDDEN STORY OF CANCER" by Brian Peskin. It opened my eyes to EFAs and the importance of PROTEIN (good!), and CARBS (bad!).
