Sounds a little extreme as a hangover cure in itself. I've heard of it before, not sure I'd ever be tempted when force-drinking a couple pints of water every morning achieves the same result. However, stomach upset/diarrhoea where you can't keep water down (does happen at TTR on occasion) I wonder would I be more willing to pay for something like this, when you're 90% sure it's dehydration making you feel so ill (could save a trip and bill to the hospital).
