Nesting, Nesting...

Can anyone explain to me what to do with this strange pregnancy phenomenon of "nesting"? I understand that it's got something to do with a woman instinctively wanting to set everything up for the coming of baby. Normally it happens at the very end of the pregnancy, though for me it started about a week ago, and I'm just finishing up my 20th week now.

How the heck do I cope with this? LOL. My biggest thing right now is that I HAVE to clean the house, and I HAVE to clean out the guest room, which will be the nursery. We still have unpacked moving boxes from when we moved in a year and a half ago, so I decided I would actually go through them, take out what we need and put everything else in the basement. Well, turns out those large boxes contained mainly books that we don't have a place for. So they're all going in the basement. But being SUPER heavy each, I can't move them on my own. I got so frustrated because I just want the room CLEAN and READY that I sat and bawled for a while, finally getting up and deciding to go to bed because I JUST COULDN'T DO ANYTHING. (This was like 9pm, mind you).

Oh, hormones. But anyway, how did those who've been pregnant cope with this insane nesting thing? Curious minds are eager to know...
