Sherie....I had these SO badly when I was pregnant with Olivia...toture!

My OB recommended increaing my calcium and adding magnesium and potassium to my diet....which is easy if you have a Milo before bed....Milo has loads of magnesium and potassium, and of course the extra calcium from the milk.

As soon as I started this, the cramps went.

I did this in my pregnancy with Charlie and had no leg cramps at all, and so far in this pregnancy, no cramps either....

Good luck....
