Ah, the Joy of Revising

I got my revision letter for Vanished in the Night, my next Eileen Carr book. I actually kind of groove on the revision letter. My editor always starts with like a page of how fabulous I am and how wonderful the book is and the general terrificosity of the whole situation.
She then proceeds to write 3 to 6 pages of what needs to be changed. It can be a little daunting and a little scary, but she's right more often than she's wrong, IMHO, and I know it will make the book stronger.
This time, there's been a fairly large time gap between my turning the book in and getting my revision letter so I basically have not touched this puppy since October. I barely remember my characters' names, much less their motivations. One of the first things that needed to be revised that my editor mentioned was that there was too much banter.
How can there be too much banter? I love banter. I will watch really stupid TV shows with bad plots and ridiculous characters as long as there's some banter. But, lo and behold. There is too much banter in this book. Everyone banters with everyone else. My detective hero banters with his partner about lunch plans, for Pete's sake. It's bad banter. Pointless banter. And what's worse, it makes my hero look like some namby-pamby arugula-eater with a touchy stomach. How not hot is that, I ask you?
She also mentioned some repetition in internal monologue sections. Ha! I thought. No way.
Oh, yes way. For some reason completely unknown to me, I have a scene where the heroine leaves one place thinking about something. There are then two scenes from other characters' POVs. Then I return to her as she arrives where she's going STILL THINKING ABOUT THE SAME F*CKING THING!!! Was I on crack? Drunk? Just out of my mind?
This is where the revising thing falls apart for me. When I look back what I've written and can't imagine what I was trying to accomplish as I wrote it. I know it's going to be okay. I can be ruthless during revisions. Still, where was my head?
Do you ever read things you've written and wondered what the you were thinking?
