What Causes Involuntary Movement Of Arms And Legs While On Ropinirole?

I was diagnosed by the VA for RLS. They starded out giving me a medication I think was caled Pramiperole. I took two tablets daily. It worked great. Then they told me that this drug cost too much and switched me to Ropinirole 2 mg tablets a day. I now have to take 6 tablets daily. 2 at 06:00, 1 at 12:00, 2 at 18:00 and 1 at 24:00 hours. Ropinirole makes me drowsy, cannot sleep, involuntary movenent of arms, shoulders, legs, feet etc. VA does not try to find a cause for any symptom. They just send you home with a bag full of cheep drugs.
