Good luck. Hope you complete it.
Longest fast I ever managed was 12 days. Target was 14 days, broke after 8 days the first time - wife told everyone that I was killing myself thru fasting 😁 and when word got to my mom all hell broke loose. Had to break it off then and there.
Second time, wife was more understanding but I just got bored after 10 days and ate some fruit off the counter absent mindedly while watching something on the phone. And that was that.
Third time, I was determined to reach 14 days. But on the 12 day I got clear messages from my body to stop it. Felt weak and hungry, so broke the fast.
Nowadays, I stopped attempting long fasts and do ADFs with rolling 48s & 72s and that seems to work well for me.
