My husband has been using Ropinirole for 5 years now but the doctor has reduced this and added Levodopa. I have noticed a big change in his physical movements. His head is moving side to side and he has a tendency of walking with his head cocked to one side. We just finished a 10 day trip with friends who never noticed his tremors (not very observant on their part - but that is a different story)...but they really noticed this different movement behavior. I am very concerned. Is this common?
