I don't know how many of us experience this, but I am also one of them. In my case I don't think that it is due to the mechanics of chewing. I very rarely experience it at home and maybe about half the time when eating out. I really had not thought about the vast majority of the occurances being while eating out until I went to dictate this answer. It might be interesting to try and find out what the active factor(s) is/are. Bruce 56/9 Sinemet and Mirapex <Now known as Alpha Centauri on the #parkinsons chat channel>
