Hi Claudia, I haven't had spit for over a year now. I carry a bottle on a waist belt and take sips all day long, often holding the water in my mouth for long periods. Sometimes my hands are dirty, so I can't grab the bottle. My cheeks will stick to my gums, and my tongue to the roof of my mouth, which makes it hard to talk. It really sucks, but I just deal with it.
When I eat, I drink just enough to get the food down. Some foods go down easier than others, so I look for those (steamed veggies go down real easy for example).
The drugs Salagen and Evoxac don't seem to help me much, but may work for you.
O-O
