I go with the "drink as much water as you drink alcohol" or "drink a glass of water an hour before going to sleep".
I think the second one is a cheat because it just makes sure you don't fall asleep drunk (or you are at least sober enough to drink some water and then wait an hour to fall asleep drunk).
Your two friends look really familiar to me and I have no idea why. I'm probably just crazy. And yes, you could have asked either Nicki or I and spared yourself the pain. Drinking a bottle of wine before ANYTHING is a bad idea. Haha.
