Leg cramps?

Hillary • I'm a preschool teacher and have been married for 5 years to the love of my life.
My legs cramp up and ache so bad through the night that it wakes me up and forces me to move them around and switch positions constantly. It's gotten so bad over the last week that I dread bedtime. My husband can't even sleep in the bed with me because I toss and turn so much. Any suggestions for relief? I already looked it up online but didn't really find any helpful advice.
