Donna, I had similiar problems with stiffness, freezing and especially painful toe/foot cramping. After many trials and errors we realized that these episodes came mostly during the bottom cycle of the med. ( In other words, as the dose was waring off and before the new dose took over) We agreed to experiment and liquidify the sinemet which meant drinking a measured dose every hour or 1/2 dose every 1/2 hour. Quite honestly, it worked really great the first 8 weeks....which means that the episodes lasted a shorter time and were not so severe. That began to wear off a little now into my fourth month but its still better than it was at its worst. This method of taking Sinemet has been tried by many members some with better results than others...but hey...it's worth a try IF YOUR NEURO AGREES AND GIVE YOU THE INSTRUCTIONS. Good luck Joyce
