Hello, I have a question for you. My father 66/1 is on Sinemet 100/25, for times a day. 2-1-1-0,5. He had a lot of problems sleeping, but now he's taking 0,5 Sinemet at bedtime, it's improving. His main problem is that he experiences a lot of pain when he is sitting. So he tries to walk of lay down. I don't know if his muscles hurt or what. It's is difficult for him to describe exactly where the pain comes from. Does anyone recognize this or have an answere what we can do. Thank you . Gerdie Ketelaars
