You know what Bill and I do that helps a "little"? Not alot, but a little. On the day that he commutes out say on a 3 or four day trip,,, I always pack him a lunch and he eats it in the crew lounge before he flies,,, believe it or not it saves us a little money,,,, the thing that is REALLY different you and Doug is that you guys are having to go "back" to doing things from the past which makes it really tough,,,, for Bill and I since he is still in his first year,,, we dont really know what we're missing out on because we haven't gotten to have it yet ya know? Bill doesn't sleep in the lounge BUT he doesnt have to get hotel rooms either,,,, luckily his mom lives in ATL and he just takes the MARTA to her house when he needs to.
Instead of cutting out something completely like eating out,,, or the movies, try just cutting back at first,,, instead of going cold turkey,,, Going cold turkey,,,, could hurt
Good luck. Let us know if you come up with any other good ideas.
