Thanks chopper! Worse than that, I get cramping in muscles around the joint and have no choice but to get out of bed and walk it off. Hate getting "old" but it's nowhere near as bad as the alternative.
I don't like the leg cramps that wake you up and flip you out of bed, especially since I have a step stool to get into my bed. One of these days I guess I'll have to put the mattress on the floor, I'll be too old to crawl UP into bed.
