I think you'll find that its much easier to travel very long distances without being *totally* sloshed.
When I'm going domestic, I drink drink drink drink lots of G&Ts. However, on international, I'll have the pre-flight, and a cocktail, maybe a glass of wine if it isn't bad, with dinner and that's it.

On my last flight to TLV, as I was doing my pre-landing freshening routine, I looked at the alcohol usage report, and 95% of their stock was unused. The FA said she usually works domestic and they go through more alcohol on a 737. I told her that jews aren't shikkers.
