I have been one the verge of "burn-out" for months now. I've been working 52-60 hrs. a week, working on "honey-do" projects at home until its way to dark to see, getting maybe an hour of wind-down time if I'm lucky then dragging my ass through the house and passing out in bed...just to get up 4 hours later, bounce of the walls to the shower and do it all over again. It's rougher the older you get. I definately reccommend that you get some rest now...before the baby, because after that, a good nights' sleep will only be a dream.
