After drinking 4-5 pints of beer would 2 pints of water, 2 banana and half a teaspoon of salt rehydrate you? or would you need more?

Would help but...: That sounds like a helpful measure but I doubt anyone knows for certain just how much of those would be needed. While it may be occasionally OK to drink that much beer (as long as you don't drive afterwards) I'd encourage you to only do so on rare occasions.The latest research shows averaging more than 1 drink a day has negative consequences, increasing risk of cancer, liver disease, diabetes etc.
