Steffi, if you're feeling worse and having more shakes, it is the Requip's affect. When I reached 12 mg per day I felt worse and worse until I had slowly, slowly cut down to where I felt good again. For me it was at 8 - 8 1/2 mg daily. Less may help you better than more. When you decrease slowly, you will know when you have reached the daily amount that helps you the most.
Requip increases tremor, makes you ache, hobbles your feet even if you only are taking .50 mg too much - not .50 mg too much per dose - but at .50 mg per day.
And do get a pill cutter - or if possible - get a prescription for a portion of .50 mg Requip..
What a bother, what a tzimmes, what a pain this illness this is,
