This, but with one twist: "... plan through how you could lower your expenses if the hammer falls."
Don't just plan - implement that plan now. You won't be any worse off, and will be much better prepared if the hammer actually falls.
If the hammer does NOT fall, then the money you saved while in this mode is just a nice little problem to have - pay down other debt, save it, etc...
I went through the 2000 .com bust and learned this lesson in time for the 2008 slowdown. It really helped and also allowed me to trim some unwanted expenses long term.
