dreadful things. Every single night (except the last 2 - touch wood). I've had those cramps, particularly in my left foot the last month atleast. I'm hoping they've disappeared now.... The worst thing is they turn up while I'm asleep, so even if I've managed to sleep through and not needed to wee, I'm totally awake once the cramp hits... All I can do is wriggle down the bed and push my foot down against the bed rails to stretch the muscle out again.
