Had a pretty strange experience at the airport just before onboarding.
I took a cold drink as I was super thirsty, and had the urge to pee right before going in. I have to state that I usually can hold for very long times on this topic, especially as it was not that strong there.
For some reason I thought about the file (a video file version with "watery" sounds to push you to pee, I used that the other night I described as I wanted to pee as fast as possible) and had a very strong urge to go to the toilet as I could not hold while thinking about this hypno...
Funny side effect and unexpected as I did not listen for 2 weeks to it, I have too much work the upcoming days so I cannot use the files again but I will definitely do it and see how it goes.
I keep updating the thread with my personal experiences as it gives hints about what it can push you to do / think.
