Everything I wanted to say has been said, so I'll just add that "magnesium tea" (magnesium citrate powder mixed with hot water & a little cool for tasting) is a fab muscle/mind relaxer. I get the kind called "Natural Calm" - always knocks me out if I'm a little tired to begin with and just can't manage to fall asleep. It's essentially a magnesium supplement, so I don't think there are any medication contraindications, though it's always a good idea to check WebMD or similar beforehand.

Good luck!
