Thank you Nate.
What's really driving me on are Belief and Curiosity.
The Belief in the books I read (eg Dr Jason Fung and Dr. Sergey Filonov) that their methods are safe & beneficial and the Curiosity to experience the process & outcome for myself.
We are living in unusual & unpredictable times. Having the confidence & capability to function normally for up to 2 weeks without food intake is a precious skill to have.
