Yeah, sleeping can be annoying. You consciously feel like you’re not tired and you can do anything, but you still start suffering the effects of fatigue.
Usually I sleep an average of 5 hours while fasting. In the case of that journal I never really stabilized if I recall correctly.
Low intensity movement like hiking is great during a fast. Since fat-burning delivers energy a bit slower, doing low-intensity stuff makes it so the body can keep up with the energy demand.
I never managed a Master Cleanse. Tried it for a bit but it wasn’t my thing. I did take away the saltwater flush from it, which I usually do on Saturdays when I’m not fasting.
I’m still working towards fasting 3 consecutive days every week.
Finally, remember to refeed properly.
