“Smile” and “nodded” are both on my ctrl-f list when doing a pass on a story. I know your pain! ;_;
I tend to use these quite a lot too, mostly “very” and “really,” along with “just.” I don’t even need that word half the time, yet I use it way too much.
That’s one of the reasons I heartily endorse and use the Hemingway Editor. You can use the online version for free, just google ‘hemingway editor’.
