Hmmmmm - I suspect it may not be quite as simple as that. Most of these drugs which have serious (potential) side-effects also seem to be prone to withdrawal symptoms: thus, while your PD MIGHT not have been benefitting a great deal, your body was accustomed to the intake, and told you loudly about it when discontinued. i do know that Pergolide and Ropinirole both have warnings that you should not discontinue them except under medical guidance! -- Jeremy Browne, Hampshire, UK [log in to unmask] Shaking Hands BBS, Fidonet 2:252/160 (+44 1252 626233, also FAX)
