As I expected the pain just lasted less than 48 hours, will pay attention to this weeks loop if I get again a response from my body to the sub.
And @James i still find it fascinating to experience that, even though it is audio instructions to the brain that I cannot understand with my conscious, it still has an affect. No need to understand why for me, I just continue and am happy to have and know about this unfair advantage to the non-sub people.
