My first dry fast, I aimed for 72 hours. I broke at 68, because birthday cake. A few weeks later, the warts covering my right foot had died, half already fallen off. A few weeks more, and it was as if they were never there. I was fasting to grow in Christ. I was caught completely off guard by the wart thing.
Also, whether it be dry or water fasting, it makes my sleep apnea go away.
