That's interesting, I used to take magnesium tablets before I was pregnant, I was getting leg cramps then, I had a magnesium deficancy, when I got pregnant the doctor said to stop taking them, I see a new Doctor tomorrow, I'll ask him what he thinks as I'm still getting bad leg cramps, every night and my legs are sore constantly during the day, I've heard drinking water help, which I'm doing and yes I eat bananas, the tablets do help, I wonder what this doc will say, take heart they usually go away when bub arrives Stretching and walking help a bit too.
