WOW, that's a lot of sleep! ;) Well I definitely didn't feel this energized on day 1, it probably came about day 4. I think the main thing is that I did raw veggies for about 10 days and I don't think that my system was as toxic as it had been in previous fasts. I didn't have any kind of headaches, or nausea, or a severely coated tongue like I usually do. Have you fasted before? Did you experience the same fatigue? I hope your energy level comes up a little like mine did after the first few days, good luck with the rest of your fast!
