What will you do when get up with a cramp calf?

I have definitely had this problem before. What I do to even prevent that is to just stay hyrdated through out the day and try and take Vitamins. You also need potassium in your body because the lack there of causes cramps. But when it does happen some things you can do that works for me is take an asprin right away, drink it down with pickle juice and eat a bannana real quick and it goes away within a minute
