I started a fast on the night of February 1st and finished on the morning of the 22nd.
About 4 days in I had a clear runny nose. Several days later it went from clear to kind of sticky and yucky. I used a sinus rinse bottle a couple of times. Around day 15 everything was completely clear and I could breathe so freely it was amazing.

Two nights my hips ached terribly. Then they didn't anymore. Just like that. They stopped.

Mentally it was an thing odd for me. Every time I had a symptom I would think, "Oh, no! I bet this is going to last the whole time I fast." And then it would go away.

Not to get too deep but I realized I do that with things in my life sometimes. If I have a stressor or something negative I think it's going to last forever.

Fasting is very personal and enlightening. I am thinking about starting another fairly soon.
