I have some good ideas for you as far as how you can get calcium and magnesium into you without these problems. I hope you have a juicer, if not, it would be a wise investment. They don't cost too much anymore, especially a small one. For calcium, juice Kale, parsley and broccoli. Always mix them in a 1-4 ratio with carrot juice. For magnesium juice carrot, apple, beet, broccoli and brussel sprouts. If you combine some from each group you will get both calcium and magnesium.
