A gaming layer with the entire left side “shifted to the right one” so WASD falls on ESDF has worked well for me. I use a quick toggle layer on the right hand side to switch back to my typing layer and then back to gaming if I need to type something up in game.
A friend of mine is a Doctor. This is what he suggests to anyone who is truly interested in stopping.
He says this makes it accessible but inconvenient and not as enjoyable. Eventually the inconvenience will start to outweigh the need until you end up quitting. He says he has like a 80-90% success rate with those who actually follow through
