"Please, update here , on which day and also what number of the fast !"
7.9 days for me.
I believe you are asking how many times we fasted before? I was reluctant to answer this but in the spirit of providing information here goes...
My first fast was 2 days and 5 hours and i thought it was the hardest thing i had ever done in my life. This was for spiritual reasons and was about 17 years ago.
Soon after this came 3, 5, and 10 days, then a series of about 25 "7-8 day" fasts over the years with one that i felt strongly compelled to break early at 5 days. Also in that time was a 14 day fast which included a drive up the coast of California, a 4 day stay in Redwood National Park and a visit to San Francisco among other places.
About 15 months ago (it really seems like longer but it wasn't) i discovered this forum and through the knowledge and confidence i gained, most especially from the fasting wisdom of Chrisb1, i was able to fast 10 days then 30 (to completion!) then 30 again (not to completion).
This current fast which is going very smoothly at the moment i intend to attempt about 30 days again unless i reach completion first or encounter some other reason to end early, or unless i am feeling great at 30 days in which case there is an excellent chance i will continue deeper like my hero Waterdesign : ).
