You can drink some crazy amounts of booze and yet still have no hangover if you down enough water in the process. A lot of water actually.
Best tip is to always go to sleep with a full glass of water by your bedside. The difference between a hangover and not having one (or a much, much LESSER one) is taking a few gulps of water when you wake up during your sleep. It only takes you a few seconds, so if you do get the chance then take those few sips before continuing your sleep. As mentioned, definitely put a glass of water by your bedside before you crash out...
