I have met and know a number of actors, musicians, bartenders, and others that travel for music, plays, cruises or the like. I also know a number of sober bartenders. Each of them have said that it wasn’t easy in the beginning, but it can be done. Each of them note that they had to have a plan going into situation, making meetings when at port organizing meetings at sea for staff.
Whatever you are doing now, my advise would be to be proactive in trying to create a plan to have at least some of those more important habits in place when traveling.
