Each day will be different and some days your fast will be easier, as you body refreshes, renews and reset its self to that way it should be.
Nice profile pic of the Easter Island head.
Keep it up. I liked the part about that doctor not believing you have been on water for 10 days. It is amazing what doctors do not know. LOL
In 2006 I fasted 55 days on water over the Lenten Season. It was a very life changing experience for me. I am glad that I did, it because it changed my life.
