Lotta good advice here. Will still add my 2 cents.
I was in a similar boat, last job involved zero nights away. First year was a kick in the junk for all of us. After that period of adjustment though, wow.
Here was the hard part for me--lack of imagination. Other than flying, there is zero commonality between being an AF pilot and an airline pilot. It was hard for me to figure that out. Walking off the plane after last leg/day has a feeling of freedom like no other. There is nothing for me to do, no anything packages, no email, phone wont ring (and if it does Im under no obligation to answer), no nothing till its time to go back.
Nights away were tough at first, but not as much as I thought. And we all adjusted. I work too much, domestic narrow body line holding works out to 4 four day trips at worst. Thats 12 nights away from home. No joke, but then you have to add up all the other hours home. It is amazing what you can do with all that time.
As has been said, living in base makes this a completely different job.
