I have two friends, Dorothy and Jack, (mid to late 60's) living (not together) in the Caribbean--both of whom have been diagnosed with Parkinson's Disease in the last two years. They are both currently taking Sinemet CR which has relieved initial symptoms, but both recently are experiencing pressure in the inner ear (the side of the body on which they are most affected)--has anyone else experienced this? Also, Dorothy has been suffering from diarrhea for at least three to four months (she's been on Sinemet CR since the end of 98). I noticed a couple of archived messages that refer to the unusual, though not impossible, link between Sinemet and diarrhea--if anyone has experienced this and has suggestions, I will pass them on to Dorothy. Thank you.--Jane
