Kirsten at the top of this forum there is a thread by Karen called 'Hot Links!' in it you'll find all kinds of questioned answered, including this one This is the link from that thread that helps with supplements, specifically potassium, calcium and magensium It will tell you how much and when to take them. The potassium will help with the fatigue, but it is the mag and the calcium that will help with the cramping - you need them both.

Have you read the book yet?
