That is exactly why I have not written a novel yet. That, and staying with a narrative style that long.
Dialogue has never been hard for me, though.
I don't know...I think my problem with detail is not how much, but of what the detail is about. For instance, I might go off about, say...uh...hot dogs or something while character is talking to someone.
Uh...Well, I can see I have been no help to you whatsoever, and confused myself even more in the process. Anyways, just pretend I am not here.
