dietary supplementation
"I read that L-Arginine could be helpful for night-time leg cramps.  Mine began suddenly, occurred several times nightly, usually in my ankle, groin, toes, and tibialis anterior.  I took 1 or 2 500mg L-Arginine and they stopped almost immediately.  However, during the 2 months that I took it, I experienced extremely heavy menstrual bleeding with clotting.  Stopped the L-Arginine, haven't had any more cramps, and the menstrual periods have returned to normal."
