We used to call it "Post Opera Depression" when I was doing community opera performances. (POD for short, Post Tour Depression doesn't make a catchy acronym.) After "hell week" (named after fraternity pledge week) in which you were almost completely immersed, finish the last show, help pack up sets and costumes, and show back up to work Monday morning. Without that immersion, we felt adrift for a few weeks. Then it was time to pick up the music for the next show.
Start with a couple weeks of down time, keep your bike rides to <20 miles, let your body recover.
Catch up on all the issues of "Adventure Cyclist" you haven't had time to read.
See if there are any good journals on crazyguy you want to read.
Pick out two-three tours, or touring outfits, that sound interesting, and read about them when you're feeling adrift.
Oh, yeah, pay some attention to that j-o-b thing that's going to give you health insurance during your next tour and the financial wherewithal to do it.
Bosses like that. And you want to keep your awesome boss happy!
