My wife used to travel frequently for work at times for the whole week, and I too would look forward to her trips so I could drink as much as I liked. Of course there was hell to pay when she returned, but I didn't care. AA is not an option for me either. What does work, though, is a commitment to sobriety, a well thought out plan for those dangerous times as well as when all is well and complacency sets in. I don't think it has so much to do with "finding something to do" as to having the calm that comes with sobriety.
