Did this also a long time ago. I still have my laptop connected which I flip open to use the webcam occasionally but I feel much more focused using 1 monitor.
A decently-sized 4k display allows you to have documents open next to your main work app when necessary, but equally lets you use the full real-estate when you don't want to.
With two monitors, I just found myself shoving shit on the second screen and getting distracted.
