One thing JB stresses is having a safe home base, and always being prepared. If all the food you have is of the quality, clean nature, I don't see the need to obsess over it. I always bring, no matter where I'm going, enough clean food to last me 6 hours, usually in the form of beef jerky and mixed nuts.
It sounds like you're a Type A personality like me - highly detail oriented and motivated, sometimes to a flaw. One thing I found I had to get away from was mindlessly hitting nutrition goals and doing doing workouts no matter what.
Truthfully, I believe if you've been training long enough and know how your body reacts to certain stimuli, you can make intelligent choices within a specific paradigm. Whether that be specific training patterns or specific nutritional goals, I think a person needs to learn to eventually get away from a nutrition log (although I think a training log is essential.) Don't be afraid to experiment and don't be afraid to relax - that medium pizza you eat (not that you do, but I'm assuming) on Sunday evenings won't kill you. Sometimes we type-A people can conspire against ourselves, become so frustrated and so focused, we lose sight of the forest, lost in the minutae of the bark composition.
