They tell you in health class that there's nothing you can do to make a drunk sober up more quickly, however ascorbate in large doses does a great job. (Avoid the sugary stuff. Sugar prevents the absorption of larger doses of Vitamin C.)
Here's one study suggesting that ascorbate may allow morphine to be used without danger of dependence or addiction, with the analgesic effects preserved.
