You are quite right when you say that ...recognising when the body, but mostly the mind and spirit (for me this time round)is/are ready and wanting and needing changes ...then the fasting is easier. I am 10 days into a Water Fast of indeterminate length. The start of this fast was magically so easy.....having prepared myself physically and mentally for it over a period of a few weeks. So from day one, I was off and into it, no problem. I feel GREAT in every way.
