Pickle juice stops leg cramps at night!  PSA

I have had leg cramps in the middle of the night. Painful ones so bad they seriously were harming my sleep. I was told by a friend to try drinking some pickle juice the next time. For me it was instant relief. I mean that I could feel it loosening up by my third sip. It sucks walking to the kitchen all groggy, and I dislike drinking the juice, but if I can do a couple of shots of tequila, I can take the juice! No hint of it as a cure on any first page results on ddg.
