Or maybe consider setting it all aside for a time; six weeks or so, and then coming back to it? I would say "hang in there," of course I would! if it didn't sound as if you were involved in a full-scale mutiny!

But maybe this is the way it goes for you, and so is good, but I usually question the use of "more" when what you're doing isn't working out so well. Or maybe it is, I mean, it's hard to tell from here, of course :)

But good luck and love with your book, and no matter what, you really can get through it.
