Wait for it!
This is an older video of writer Elmore Leonard but I really like what he says in the first minute about getting up early to write and delaying his first cup of coffee until he's written for a while.
I don't have that kind of willpower. I can, however, not get a second cup until I've cranked out some stuff.
On the other hand, I don't have a problem with using a verb besides "said" to say that someone . . . said something.
Just keep writing.
