I have had Parkinsons for approx. 10 years and have been on Sinemet and more recently Mirapex, I am generally knowledgeable of proper doseage to avoid DID and IDI and dont believe medication is the cause of a recent experience of hiccups. Can this be a result of Parkinsons disease or another underlying cause? The hiccups are persistent except for an inconsistent reprieve at the height of an ON period. This inconsistency is what puzzles me. Any ideas would be appreciated. Thanks in advance. Vic
