I try to bounce back immediately after the meal in which I slip up. I have only been on sparkpeople for a little over a month, and the first big slip up I had made me feel so much like a failure. That time I didn't start back until the next day (but I'm happy with myself for starting back.....I posted some spark messages and got some great motivational responses that helped so much.) I didn't do very well today either (at lunch mainly) but am now determined to get right back into my new healthy habits. In fact, I am about to go exercise!
