I assume you mean while writing? If so, YES.
As a matter of fact, I found a place where I did that about a week ago and I forgot to go back and fill in what I skipped. I face-palmed at myself …
When I start experiencing fatigue, I usually write: baba black sheep says: babababababa within the text box I am working on to tell myself I need to go back here and fill it in.
Usually, if this happens, I will end up working on the related mechanical structure to revive my interest and if that fails, once I’m in a “safe” place, I take a break for a bit.
There is a couple of things I do when I start bababaing
1st - I take notes on what I’m thinking at the time this is happening - storywise, characterization, etc which I can use to refresh my memory when I come back to it…
2nd: I keep a journal where I try to keep note of the lines I do this on. Which sometimes I forget to do anyways.
