Hi John, I liked your comment about yawning. I would like to add a little to it though. If yawning does 40% of the relief, then sneezing does the 60%. At least according to my father (66) who has had PD for the past 10 years. He wishes for a yawn, and he prays for a sneeze!!!! Thanks for your info, H.M.Laswi San Jose, CA [log in to unmask]
