I started taking a magnesium supplement called Natural Calm, it comes in a powder and dissolves in hot water like alka selter.  It's an amazing product.  I started taking it about two weeks ago, and I have noticed a hugh difference right away.  I sleep like a baby, I don't wake up during the night any more, and I do not wake stiff any more either.  My mood has improved, and I have a lot more energy, and my mind is clearer.  Amazing product, do a search on the internet for it, I found it at the local health food store.  You can buy with or without calcium.  I initally bought it without and my first week was amazing,  I hadn't felt so good in more years than I can remember. but I think I got a little out of balance by not getting enough calcium, so I bought it with calcium for the mornings, and take it without calcium bofore I go to sleep, and it has worked out great for me.  The calcium combination gets me going in the morning, and the magnesium only forumila puts me out like a light at night.
