Leg cramps?

Is anyone else having leg cramps? I take my vitamins, plus calcium like I've read online to take for cramps. I'm trying to up my fluids and drinking Gatorade with electrolytes. Something has to give! I'm having cramps from my hips all the way down to my ankles. I try to stretch too and walk even extra before going to bed. But I'm waking up every hour with cramping.
