Naomi, I started getting these about a week ago, so you're pretty much on track LOL! They are an absolute bugger, nothing like leaping out of the bed half-asleep at 3 in the morning yelping cos you've got a cramp in your leg/foot! I had one the other night that left me sore for two days OUCH. I will def. try the mineral water. I've had two chemists say that magnesium hasn't been tested for safeness in pg so weren't prepared to sell it to me. I keep meaning to ring the RWH drug line tos see what they think.

I'm sure it's fine though, lots of women take it. I hope they ease up for you!
