I had a lot of the same issues extreme fatigue cramping of limbs now I do suggest you go to your dr but what my Dr found was that I was critically low in my B complex vitamins, thiamine is a huge issue for those of us that drink to excess. He gave me a shot and within a very short amount of time I was feeling so much better, you can get them in any drug store. B complex.... can't hurt to try them but please do see a Dr as well to make sure nothing else is going on
