I'm just finishing up day 8, feeling fine. Yes, I suppose I could go on a little longer. I think about food but can't say that I'm really craving it yet. And its really amazing how much extra time I have in a day when I don't have to worry about eating! I just posted a question and I'm wondering if you're having a similar experience... I have a very strong metalic taste in my mouth (for the last 2 days), and no matter how much I brush my teeth it just doesn't go away. Have you experienced this?
