You sound just like me! My stomach growls no mater what (day 4 almost 5), but I know it does get better after the first few days...fasting... I know that headaches and all can be symptoms or dehydration but are symptoms of detoxing and lack of food for some. I always get headaches when I go without eating, but strangly when fasting they EVENTUALLY stop! I too have been having headaches as well as other symptoms,I had such a BAD headache today I was in bed ALL day, my symptoms have been SO BAD the last few days, I have been told by several on here NOT to do coffee enemas while on MC, but today I was having pain in my liver and my head was hurting SO BAD, I did a coffee enema and passed 2 MARBLE SIZE stones (like I do on liver flush) and my headache not only went away, I felt good tonight for the first time in 4 days!...take care and rest when you can, i know ALL about that no sleep! I t will get better!
