DONT GIVE UP!
I've done the "cleanse" several times over the last 2 years as a diet/healthy eating quick start. Don't make excuses to stop the diet. I've always lost between 12 - 16 pounds and I generally gain about 5 back a few weeks later. That still leaves me down at least 7 pounds. It hasn't screwed up my metabolism.
Stick with it, you will feel much better once you shed a few pounds.
This time I'm not going to drink the laxative tea because it is a pain to make sure I'm near a bathroom. I hope it has the same effect.
