There is an earlier post suggesting quinine. I used to have severe cramps in my feet and calves of both legs. My pharmacist recommended quinine. I asked my doctor and he said I should try it. Well, I did and I take one 200mg capsule at bedtime and it works! A couple of weeks ago I thought I was out of the woods, skipped three nights and you guessed it....terrible cramps in the middle of the night. I started again and have been fine since. Good luck.
