Boy, I know the feeling. I am on day 7 and already feel the urge to break.
I have never had the Oxy experience, living in Mexico and having scant access to products. Had to do things the "ole fashioned" way!! lol
If you are low, it sounds like you are doing detox. Hey! It's day 9! Can you not gut through and see if day 10 doesn't bring you up before you break? Try a hot cup of mint or chamomile tea. I find that very comforting and satisfying when I am having a rough spell.
Is your colon April Fresh? I did an advanced cleansing procedure (as in, not Master-Cleanse protocol) and got a lot of gunk out--felt like a million bucks thereafter. Make sure you are flushing flushing flushing.
I have been reading a very interesting concept all morning at http://www.fast-5.com.
Go, look at the FAQs, and especially read about the people who put this together! Download the Little Book and read up. I am very interested.
This should distract you! If you just can't take it anymore, distract yourself by making soup. Drink OJ all morning tomorrow then go to soup. What the heck. If you still need more cleansing, you can do it through diet if you stick to stuff like you say you are craving.
