kid-A GATOR-ADE and LOTS of it !!!
Not that I have ever let the weaknesses of the flesh allow me to consume alcohol in such excess, but .... ahhh ... I have had people tell me that the Gator-Ade thing really works. And yes, maybe 2 or 3 quarts (liter)s will help.
I have also been told that a few extras hours sleep works well too.
Others have told me that they have come up with interesting excuses for not going to work the next day.
I have heard that others, especially if it's on the weekend, simply start the morning where they left off the night before and the headache seems to go away!
I hope my gathing this information from the experiences of others has helped.
