Will stay on it.

I have done it before ( 1 year or 15 months ago something like this) and got to the point were you are supposed to take the 10 min cold showers but I couldnt do it after trying for several weeks I got less and less consistent and gave up eventually.

The cold showers sticked though.

I feel the same way as you, more energy, motivation and I feel kind of powerful espically after the breathing.
With this open diary I am sure I will stick to it even if I will repeat some weeks for years :-)
