I'm on Day 7 But Baffled with my results!? Help!

This is my first Master Cleanse and I have followed it to the letter. I haven't cheated = not even so much as a breath mint or stick of gum. I've taken 6 measured glasses a day, plus the tea before bed and the SWF (Salt-Water-Flush) every morning. I lost about 3.5 lbs over the first 2 days but have gained back almost 2 lbs of that. How am I not losing when I'm taking in 700 or less calories a day??? Other than that, this has been rather uneventful and easy for me. No 'ropes' or odd discharges anywhere. Is this 'normal' or am I not getting good results?
