I find my creativity improved when my mind is tired, but once my focus returns and my dopamine levels are lower the following day, I tend to conclude that what my mind wanted me to create wasn't actually all that good...
I got the similar result, the thing thing my brain fancied earlier doesn't seem so great after the dopamine falls away.
But, I found that if I persisted with trying to create or refine the earlier idea, very often there was something good to be found, not always directly related. I might just be seeing a different part of the application code from a new perspective by trying to write a new feature using the same libraries, and go in and get a gain where they're used elsewhere.
