Add my voice for recommending moderate amounts of alcohol. A few drinks, my noise-reducing headphones and music on my iPod makes the time fly by, primarily by letting me sleep. The problem with alcohol is that it dehydrates you, so drink plenty of water or fruit juice along with your drinks. Noise reducing headphones are invaluable -- it creates a cocoon of [relative] silence that you can fill with your own music. My wife uses them without music -- just the phones alone allow her to arrive refreshed and relaxed.
