I hear your frustration! I was on a three year plateau. There are so many tools though to shake things up again. I'm active with the 5% Community (Champions in the Kitchen). I also added the Spark Coach program.
I started this program when I weighed 460 pounds with a 66" Waist! I got serious with Spark People when the scale was creeping up to the 300's again. That was 187 pounds ago. I am confronting all the little demons that have led to my failures.
Wanna know more, just ask! I'm very shy! I also sent you a friend request! Just never Quit (See my blog).
