I follow a woman from australias blog and she actually has been writing entries about quiting sugar. She's really sweet and her blog is honest. I think this could be something you're looking for! http://www.sarahwilson.com.au/2012/11/i-quit-sugar-on-a-current-affair-tonight/
I just saw a post about this on instagram. They are doing it for 14 days. I think I might try it :)
