I have dry mouth, no, desert mouth. I had dry mouth before as a side effect of non-PD medication, and the PD medication now makes it so much worse. A few years ago a friend of mine went to Walgreen's and purchased all these dry mouth products for me: the toothpaste, the gum, and artificial salivia. None of them work. Forget water and other liquids, ice chips, hard candy, whatever: none of it works or works for a very short time. When my throat gets very dry, I will cough and then I will choke. The only thing that works for me to prevent this from happening or to stop it once it starts is a medicated or mentholated cough drop. I only use one or two a day, and usually when I leave the house to go somewhere. If I am having a particular problem with dry mouth when I am out or when I am going to bed or trying to sleep, I will take a cough drop. I do drink lots and lots and lots of liquids, usually when I'm at home, usually water or something non-caloric or sugar-free. Just when I think that the dry mouth is manageable, I will have an episode where I drink glass after glass of water, and nothing works, my mouth is still dry right after drinking a full glass of water. Basicly nothing I have found works very well. If anyone has any ideas, please share them! Katie
