Store some stuff at work. I specifically take in a load of pressed shirts but you could also take your lunches or lunch ingredients in bulk. I have a coworker who brings in a couple flats of soda from Costco every month or so. That saves you from the time and mental checklist of packing it or casting about your house for it.

I cool off while I check my e-mail before I change, but most jobs probably won't let you indulge yourself so.
