The news article reporting that Cabergoline successfully controls sleep disturbances in PWP caught my attention. I was a part of the Cabergoline study in the US for about 44 months. I did experience "sleep attacks on the cabergoline (as well as on Mirapex after it was released on he market and the cabergoline study ended). I also slept on 3-4 hours at night while on the cabergoline study. Sleep pattern at night changed for a short time on Mirapex, but then reverted to the 3-4 hour /night pattern within about 6 weeks. Like all PD drugs........one drug does not create the same results for everyone. I do sleep longer at night when I am only taking Sinimet.....and not an agonist.......this is only my experience that I am reporting. Rita Weeks 56/12
