Donut's first prolonged water fast

Hello all,
This is my first prolonged water fast. I am currently on day 12, though I never planned to get this deep into the fast. Originally, the plan was for a 5-10 day fast, just to reset my body and internally heal. However, I have no hunger and daily cook multiple meals for my wife and kids. It is a very strange and surreal feeling. I occasionally add salt to my water and cut out everything else including coffee.

Weight wise I’ve dropped close to 20 lbs. I am active every day, though am a bit more fatigued when done with my activity. I sleep great and my body feels incredible, however not even being slightly hungry worries me. Is this normal and how long does this phase generally last.
Thanks.
