You know, I have been eating great the last two days (since I ended the MC) and I feel like crud, too! So don't worry, just start anew tomorrow, eat those veggi's and throw away that junk food!! ASAP!!!
Since I feel so over indulgent, even though I eat healthy and lite, I think I'll start another cleanse tomorrow or the next day. (I stopped for the same reason you did midway through day 7).
Did you "come off" the fast the way you're supposed to? I didn't - I jsut started eating! Perhaps this is why you crave the junk food?? I'm not an expert, this is just my experience :) Good luck!
