Does anyone else get random, painful leg muscle spasms?

i do also seem to get them usually at night. I call them drawing cramps because my muscles draw up so tight. I find that when I am low on potassium this occurs more often so i started eating a banana before bed time. This seems to have helped. I also keep a tube of icy hot gel next to bed and if it does occur i put it on rather quickly and it immediately goes away. Hope this helps
