Thanks for all the great answers. You were right, time and a LOT of water is the best cure! I was definitely dehydrated.  I had to deal with losing most of the day to my recovery but it was also nice to have an excuse for me and my husband to be lazy for a day. Next new years we will know to limit ourselves more. I also read that if you drink water with alcohol you are less likely to get a hangover because you stay more hydrated. I will have to try that out next time I am out for a "wild" night on the town.
