If you've got the ability, take a a few days to just do whatever you like--the key, in my experience, is to try your best to NOT think about work any more than you absolutely have to. Personally, I'm fortunate enough to have a nice
comp/flex time policy here, so after a crazy week I can usually take a 4-day weekend to handle the housework that's piled up (especially if the significant other's been busy as well), catch up on some personal projects, or just sit and veg out,
play video games or whatever. The remainder of the working week I'll spend cleaning and organizing at work and putting away all the crap that piled up right inside the shop after being cleared from the
stage.
And as a general
bit of related advice:
Whether you're a freelancer scheduling your various jobs or the manager of a shop or company scheduling and costing out your projects, you have to consider your various sources of overhead just like in any other business. Recovery time is a critical but all-too-neglected part of that. You
need time to repair and resupply your shop & equipment, you
need time to stop and say "hey, x was a problem on this project, let's figure out a better way for next time", heck, you and your employees
need time to sleep, do laundry and bathe (even if only as a courtesy to your coworkers and clients!), and eat real food. So figure out how much time you need for all that, double it just in case, and
build it into your schedule. Fight for it, and raise your rates to
cover the overhead if you have to. You and the quality of your work will benefit greatly.
