I have had night cramps for three years (since diagnosed with PD). The only thing that I could find to help was prescription Quinine. Two weeks ago my chiropractor (sports type) said that I should take "Fosfree" (nonprescription). Fosfree is a vitamin supplement. It WORKS for me, maybe it will work for you. ................................................................. Richard V.
