Pickle juice hangover prevention

I want to make my own pickle juice with the intention of using it for picklebacks with the added benefit of hangover prevention the next morning. Will I have success in the hangover prevention aspect of my plan? Or are pickles part of the reason that the brine juice works so well? A google search tells me that the cucumbers seem to be supplying most of the potassium. Has anyone been successful preventing hangovers with essentially a virgin brine?
