Yeah for the unlucky some of us when a cramp hits, nothing helped. Fuck I’ve even tried running up and down stairs at 3am. Doing full stretches etc. Turns out good chance you’re low on magnesium or potassium or maybe Manganese? I don’t remember but the wife shoves one of the 3 in my mouth when she’s had enough of my whining and I’m good for a while with no cramps at night.
