Yes! Dozens of times. I'm restarting just now. For me, there have been two problems: One, starting because it's the 1st of the month, but I'm emotionally not ready. Or two, concentrating on what I'm giving up rather than thinking of it as, "This is what I eat." Not "This is what I eat now" but that I'm a member of an unusual tribe, and this is what we eat.

So I'm back with fresh reserve -- I hope you are, too. It does work. There are dozens and dozens of happy successes here.
