yup, tiredness and too much coffee will bring on the restless leg thingo for me too. magnesium tabls ... immediate relief and keep up the magnesium tabs for a couple of days. can buy them at any health food store and some supermarkets. i wouldnt be without em but only take em when needed for a few days. dont know about bananas..that would be a potassium (K) boost. other diet suspect is lack of selenium... i live in a very selenium deficient place and eat out of the veggie garden so i suppliment with a couple of brazil nuts a day so get the selenium.
cheers.
