I tend to drink very little, if anything, on long haul. I am always conscious that work awaits on my arrival and so my focus is on avoiding jet lag. There are exceptions, if travelling with family I might have a few drinks after takeoff, 3 or 4 but that is usually about it. Being drunk is not something I like, and so avoid consuming too much.

The only time I will enjoy a few drinks in the CCR is while waiting for my connecting flight home to MAN, especially if I bump in to one (or more) of the CCR old timers.
