earlier today I read an interesting short article on how to prevent dry mouth when diving, put a thin coat of minty toothpaste on your regulator mouth-piece and that should do the trick. There is also a mouthpiece known as the SeaCure that will do the same thing.
Interesting thought, I'll have give the toothpaste a try next time I go for a dive. If anyone has tried it, let me know if it works.
thanx to
