Floridagal, you can get foot cramps from lack of levadopa (especially when you wake up in the morning) or too much levadopa. Most of us have foot dystonia in the morning, but there's also a peak-dose dystonia, which comes from too much levadopa tightening all muscles all at once. That's when we seem to walk like robots, have a hard time releasing hold of things (i.e. put down a coffee cup and let go), unbending a bent arm, etc.

Have you noticed if you get cramps about 1-2 hours from taking your meds?
