I'm also on Day 8, and the exact same thoughts were going through my head.
I've had no headache, nausea after day 2, no 'stinkiness', tongue is barely coated, and I just haven't felt too bad. I have had a lot fo sinus drainage, though. And my stomach growls constantly, except for immed after the lemonade, and I still have the desire for food. And I would consider myself a pretty toxic person.
I also hope I'm getting my 'moneys worth' too. I'm going to 10 days no matter what now!
