My husband is 58 diagnosed with PD in 1995, besides the arm tremors he now has severe jaw tremors which are driving him crazy. His jaw and whole mouth area move up and down so fast you can hear his teeth clicking. In order to stop it somewhat he has to chew gum. He is on Eldepryl 10mg twice a day, he also takes Artane,clonazepam and zanax for anxiety. Is there anyone who has had this problem and took a medication that stopped or slowed down these tremors. He is not on Sinemet because it made him very ill. We would appreciate and help given. Thanks so much, Rose CG/Bob
