Yankees, Welcome to SR! Drinking can become such an ingrained habit and associated with certain activities. Once you take a flight and stay in a hotel without alcohol, it will be easier the next time. Plan out what you will do on the flight. Read a book, do crossword puzzles etc...Plan what you will do with your down time in the hotel. Maybe in your down time on the trip, go see a movie, visit a museum etc.....and definately check in here if you feel you need to.
