I was up at 6:30 this morning, early for a Saturday, prompted by cramps in my calves. I've been getting cramps in my legs on most nights for the last 10 days or so. Thinking that it was a lack of magnesium, I have been taking Slow-Mag for the last week. I hadn't had cramps for a few days now so I thought it was working, but now I'm not so sure. Mela thinks I should see the doctor as there might be some other underlying cause. It's a real pain in the buttlegs.
