I hear you. You wanted to push your fast further and you’re disappointed that that didn’t happen. However, you were in tune with your body and wise to listen to it. Congratulations on making it 6 days! That is a real accomplishment, and you have every right to be proud of yourself. Plus, it sounds like this fast has encouraged you to try a new way of eating that will help you reach your goals. In more ways than one, I’d say your fast was a roaring success!
I realize that you’re disappointed but I find this so inspiring. I just did my first extended a few days ago (38 hours) and I want to work up to 10 days. So knowing that you were able to go from 2.5 days to 6 is incredible to me!
