Hi Jalee! Nice to have you back! Have missed you!
I suffer from much the same thing as you but haven't been dx'd with dystonia just severe muscle spasms and cramping in my feet and calves. I take Sinemet and it works very well. The other drugs (Requip, etc) didn't work at all. I also get weekly massages and my therapist focuses on my calf muscles. She also taught me a technique for releasing the "charlie horse" type cramping I get in my feet that cause them to twist.
I also take Klonopin/clonazepam which helps as well. The two drugs work together to keep the muscles from twitching all the time.
Sinemet comes in a couple different dose strengths and for me this drug has virtually no side effects! That's a plus!
Good luck finding something that works! I hate the middle of the night spasms that in my feet! Yeow!
