Hey Rooth,
You are doing an awesome job. It's good that you are modifying your fast according to how you feel and you're still committed to your fast. I haven't drank much of the Master-Cleanse the last couple of days either. I might have had 4 cups yesterday and the same today (so far). I usually drink my tea warm because it's more comforting.
So far, so good...I'm wrapping up Day 6. I am so pumped. I'm committed to cleanse for 10 days but definitely open to going longer. Actually, 21 days would be pretty darn awesome! We'll see...
