If you have the option to, try holding your nose shut, keeping the mouth closed and blow as hard as you can until you feel your ears relieve the pressure. You are equalizing the internal pressure with the external increasing pressure by doing this. Your ears won’t hurt. As you start to feel the pressure rise and sound start to fade, keep doing it until the chamber is fully pressurized. Yawn and swallow when depressurizing.
This is the same method used when diving. I hope it helps. That ear pressure can be very painful.
In addition to the bus incident. I have just finished 3 sessions and one thing that I have greatly noticed as well is my wife’s negative emotions are not affecting me as much as they usually do when she wants to rile me up. So much that it is noticeable. In fact I feel happier. Is it a placebo affect? I have no idea…
