I had run across a post here from quite awhile ago that turned up in my search returns. It was someone who had gone dairy free for some other reason, and rls left. I've dealt with rls for years, and have done the magnesium thing, but I don't have any pain with this, so it's more of an aggravation for me that can get really bad at times to where I'm up every couple hours or so. I decided to try the dairy free thing, or MOSTLY dairy free. That's hard- I still want cheese on my salads, and fake cheese is just gross! But I really believe it's helping. I used to eat yogurt and fruit every morning, but switched to eggs, and no more ice cream (augh!) and I think it does help. Still rather in the testing phase to make a firm determination, but I thought I'd pass along what might be working for some relief for me.
I did run across something that says that it's the casein, the protein in milk that could be the problem. And gluten free might help some too, which I did for arthritis anyway. I guess both wreak havoc with your digestive tract, messing up body chemistry in all sorts of ways. Too complicated for me. Trouble is, everyone is different. Just wanted to pass along a possibility that might help some of you like it has for me. So now it's no gluten, precious few carbs, no sugar, no caffeine, no chocolate, and now very little dairy. Ack!!!
