Congrats! I'm getting there. I've had some progress for July, so as of today, I've got 12.7 lb to go.
As Black Walnut said, you can check out any time you like, but you can never leave. I'd say once you get and stick below 200, then you gain honorary Clyde status. Once a Clyde, you'll always be part of the club, but as an inspiration for the rest.
