I will have to try the Milo one as well.
I am starting to get the cramps in my feet too. I ha dthe same prob with my first 2 pgs as well.
I fidn what works for me is my foot will cramp in one direction (usually toes pointing) so as painfull as it is, I just force my foot back the other way before the cramp gets to take hold. It works but doesn't actually prevent them!

I also suffered bad with "restless leg syndrom" as the midwife called it anyway. But this is soooo anoying. Basically I will lie there in bed & I need to keep flicking my legs (sort of bending & straightening but really fast) or it feels like there is pressure building up in my knees & calfs. Apparetly there is nothing I can do about it & I can already feel it happening again!
