You are most welcome to do what you think is best for you. However, I disagree with your approach. You can fast on nature made foods vs. to Gatorade and toxic drugs, but choice is yours. You will get in starvation mode faster than you think. Your decisions to fast this way is stemming from some deep fear which only you can work on. If not, please tell us what is the reason you are choosing this path?
Would you please read this chapter from Dr. Shelton's book with utmost urgency and attention. You have nothing lose but gain.
