Got a 4-day/3-night trip planned. This will be my first trip to Vegas and my first trip across multiple time zones. I would like to enjoy myself, but I am concerned about jetlag. Anything I can do to prevent it? I am off a few days before my trip so I was thinking about setting up a sleep schedule based on PST. I do not want to down energy drinks and caffeine the entire time I am there and I don't want to be tto tired to play poker. Thanks for the advice.
