@roger,
I hardly ever have leg cramps any more, months and months going by, since I know cautionary stuff.
Still, maybe a month ago I got a strong leg cramp and rose out of bed to straighten stuff out, gee whiz, and fell to the floor, smacking the back of my head moderately badly since I'd no rug there by the side of the bed.
Often you can pull out of a cramp - stretch. Didn't work that one time.
Well then, one thing I have is rugs (back in Eureka, there was a, to me, wonderful rug place, however olden, plus general come and get it place re "antiques".)
Not a faint, just no cushion.
By now a rug is by the bed.
