Done and Done

I've finished my WIP! Now I've got two months to turn my hamburger into steak or closer to home my tofu into faux meatloaf.  Unfortunately, it feels like it needs about four. Oh well, when the going gets tough, the tough, etc etc. In this case do a lot of hand wringing.  I had a great idea for a novel, at least I thought it was. grin. But once I got into it, I realized I'd created all kinds of barriers for myself, the biggest being the hero and the heroine were apart. Thank goodness for telephone videos grin.
I was at a workshop where an agent suggested after a manuscript is written stick it in a drawer for a couple of weeks or more then bring it out and clean it up. Great advise but who has time to do that? What do you do? When you're done do you set it aside and let it simmer or do you plow on through?

On another note, did you see this? If it turns out to be a real cure won't that be wonderful? Cats, they're priceless.
