It has been very hard, I really had a hard time staying asleep last night and could feel my heart pounding, I had a headache, and have been light headed. I drank water and I felt like I was about to vomit, my body is screaming for food. I was up for hours the second night and this is the longest in my life I have gone without food. I have never done just a water fast. I kept waking up thinking that I could solve my problem of hunger and just eat and then remembered I was fasting for 6 more days! So crazy, I am trusting those that have gone before that this will help kill off zombie cells and be great for my body. Part of me worries if this will mess up my metabolism that has been wonderful for years like going to the chiropractor did to me with my neck and sleeping. I haven't been as deep a sleeper ever since I went two decades ago. If it aint broke don't fix it.
