When I’m tired I stutter overall more but I have noticed that in the first 2-3 hours after I wake up I stutter less so in the last months I have tried to schedule all my meetings before lunch… During lockdown when I took meetings at home, maybe half an hour after I woke up, I felt much more comfortable with my speech and the stutter didn’t bother me that much! Than few hours later I started to stutter much much more.. really strange
