Got a scientific answer for you. The big reason that you feel so bad after too much alcohol is that the enzymes made by your liver to metabolize alcohol are overproduced, unlike many other enzymes, which shut off when there is enough for the job. These extra enzymes then start to eat your liver, unless you give them something else to eat, and the best thing is fructose, fruit sugar. So yes indeed, orange juice (with or after), bananas, any kind of fruit will lessen, although not eliminate the pain. Water is also very important, and aspririn.
