Wow! That is all REALLY great!! Your system is doing some SERIOUS detoxing. ENJOY!!! Keep dowing the water. Dirreha is your body's way of expelling toxins. ENJOY the experience...lol! You are NOT harming yourself. You are actually doing yourself a great service. The exhaustion comes from detoxing. It takes a lot of energy to "clean house"! Nap when you need to - even if it is only 10 minutes at a shot. Try to stay active - it helps burn up the toxins (and avoids boredom).
