Here's my story...it should make you feel better.
I joined WW almost 2 years ago and lost the first 10%. Then stuff happened, we moved but hadn't sold our old house yet, so we had two mortgages to deal with, we had an ice storm that knocked out our power and we ate out constantly, etc. I just didn't have the time or money to devote to WW, dropped out, half-heartedly tried some different things.
Well as of today I not only re-gained the weight I had lost, I am at my highest non-pregnant weight ever, about 20 more pounds than when I joined the first time. Yikes. But I just signed up for a monthly pass and I'm going to my first meeting in a year and a half tonight.
So as the others have said, it's better to catch yourself now than in a year and a half from now with 35 extra pounds.
