Thanks a lot Chasmo and vlhperry. I understand quite a large number of people are affected and concerned by this Obsessive Behaviour problem and sleep attacks. When I started using Requip I had sleep attacks for about 2 years. Then I developed personal methods to fight against them. Finally they disappeared. Before going over to Mirapex I am trying to find out whether I have to tackle the same problem once more and whether it is worth the effort. With Mirapex have you got better results?
