Back in about '85 I went on a ten day water fast. The first three days were incredibly hard, but after that I stopped feeling hungry, slept like a baby, lost twenty pounds, and felt incredibly good.
Actually, that's why I'm on this topic. I'm gonna have another go at it.
Sounds good @Redrock12, keep in mind though that you were 35 years younger then. I would not expect the same results 35 years later. I have had positive experiences with fasting, but then I did a long fast of more than 20 days. That was not such a good experience, and has had consequences. so take it slow and listen to your body, and your heart. best
