Sounds like you are nesting to me, I never have that kind of energy and I'm not pregnant!! (My 2 are teens also, and I agree I've had enough fast food!) Another alternative to boiling the hamburger is just to rinse it with hot water as soon as it is browned. Especially if you are not serving it immediately, removes alot more of the fat than just draining it does.
Good luck with the baby!
