I was doing 22:2 23:1 for four or five months. I liked the mental alertness and ease of following the protocol also not having to prep food as much. Now I eat from around 6am - 5pm or so and just fast the rest of the time. The health benefits of fasting I think are pretty profound I also incorporate a three day dry fast once a month in shaa Allah. So I don't worry as much about my daily fasting.
