I have found that the best way to sober up is to wait until I am not as drunk anymore. It seems this is a foreign concept to a lot of people who want food to somehow replace the pbumage of time as a dimension. I guess that is inevitable though when you are the type of person whose favorite drunken activity is to try to stop being drunk. And/or someone who has a time lock on their liquor cabinet that will only open when you have a presentation to make at your job in three hours.
