Leg cramps at night are my problem. The kind that bring you to your knees in agony by the side of the bed. I've tried everything people recommended including potassium and magnesium but only increasing my salt intake has led to any significant improvement. Funnily enough, while reading this thread I got the first twinges that announce a bad cramp is coming soon. That reminded me that I havn't salted any of my food today and, of course, none of it was processed and ready-salted. So I just went to the kitchen and measured out one teaspoon of salt into a bowl. That's a LOT of salt! Yikes! And only half of the suggested 5g. Anyway, it's by the side of the bed now with a glass of water. I'm licking my finger and dipping it in the salt to see how much I can eat before the cramp gets me. I'll let you know if it staves off the attack.
