Mirapex treats everyone differently, I guess because I am now sleeping 6-7 hours a night opposed to 3-4 hours a night thanks to Mirapex. I have been taking it since the middle of August (l mg. three times a day) My insomnia went away within three or four days. I know how it feels to lack sleep so you have my sympathy. I cannot function without adequate sleep, Edie 63/l8
