Since the orange juice post is getting so much press, I had to compete a little with a tomato juice comment. Don't forget that there's a reason that Bloody Mary's are served the next day. Something about the tomato juice - and it may be acidic properties as well as the fructose, don't you think, because orange juice is acidic as well - can get in there and make it happen in ways that a glass of water can't.
Although, I have to admit, I do chug a glass of water before going to bed the nights I've been drinking. Hydration is key. So, I feel bad about what I said up there against water. Sorry water. I was just trying to support the tomato juice. V8 works wonders, too!
