If you're remembering to take time out for barking, be sure to take care of your throat. My mom strongly recommends gargling with hot salty water with aspirin dissolved in. It's very effective, but tastes blargh. For milder throat irritation [such as post-con filker-throat], I like microwaved apple juice.

Don't forget the boiling baths with big books, where you add new hot water every 5-10 pages, followed by 10-12 hours of sleep.
