I regularly go about 2 ½ days without making a single audible sound with my voice. Friday through Monday.
I used to talk to myself a bit or sing/hum along while listening to music but I kinda stopped doing that.
The funny thing is, I’ve recently realizied that the last and first thing I say throughout the weekend are usually the same. I say “Goodbye” to my coworkers on a Friday evening, and then I say “Goodbye” to the cashier near the self checkout at the grocery store where I grab my lunch for the day on a Monday morning. It’s sort of ironic that the first thing I say after a long period of time, is something that usually ends a conversation.
I talk to myself pretty often, so no more than a couple of hours.
I used to too. I don’t even know why I stopped. Maybe at first it was a challenge of how long I could avoid talking to myself. But then it just became the new normal.
