I agree, if Shelton has one downside it would be that he was a bit one-sided with his must-rest-while-fasting ideal. If he had of been around now I think he would have had to take more notice of those of us who just can't afford to take the time out of our lives for one reason or another. Yes our health should come first unfortunately 21st century life doesn't recognise that unless you're actually on your deathbed.
I'm sure you'll do better next time anyway, it's a progressive journey and you don't have to remove any of the toxins twice! :)
