> Have you ever experienced the mental clarity of 12 or 24 hours of fasting? Unfortunately I haven't although I fasted many times for more than 16 hours and only once 24 hours. I'm always lethargic, irritable and I cannot do anything other than thinking of food. I fasted 16 hours with most hours during the day, during the night, same result.
