Great question, Zoesmom,
My answer to ' what sabotages my success' is boredom. When I get bored at night I tend to graze the pantry. A few chips here, a handful of crackers there, whatever I can grab.
This time is different, I have cleared the pantry of all my 'go to' foods. I keep a pair of dumbbells within easy reach, when I am bored watching TV and have the urge to graze,I grabbed the dumbbells and do bicep curls.The urge soon passes and hopefully I will have really toned upper arms
