I used the PCT when I was behind a really slow truck on a back road. I caught the ego as it tried to create a story about me being late. I immediately labeled it "slow driver story has arrived" and continued the protocol. I listened to the Nada and neutrally labeled it, while doing my 4-4-8 breathing and affirmed "I am the awareness."
I have noticed that the ego gives up a lot faster the more you use the PCT. It may be difficult in the beginning, but don't give up! Keep training that muscle.💪
