Try upping your potassium. Since I've started eating a banana a day my legs cramps have completely stopped. It's worth a try!
Increasing salt can help too!
I've tried the banana thing. It doesn't help. I think thats because I'm not deficient in potassium. I'm pretty sure I am really really lacking in calcium. The only time I get the leg cramps is when I forget to drink milk that day. I also think that the calcium deficiency is what was causing the heart palpitations...because when I get enough milk I don't have them.
This is a total self diagnosis though..knowing what I know about hypocalcemia I think that it is probably correct.
When you do get them, try pointing your entire foot towards your face... it always takes mine away right away and stops them from turning into charlie horses!
Jenni...I have been having the same issue, I had some in both legs when I was.sleeping two.nights ago my legs still hurt.!!
I also do what Krystal does...I have only gotten them a couple times but as soon and I point my foot up they go away. Good luck!
