to 3FC!
You've got to figure out why you are overeating. Is it really because of pent-up hunger? Was it "just" letting loose on vacation, and you overdid it so much that you can't get back on plan? Or is there something else going on your life that's causing you to turn to the comfort of food?
You'll find a lot of tips on these boards about keeping motivated, and also support from community members. However, although 3FC folks can tell you to put down the doughnut ("PUT DOWN THE DOUGHNUT!") as much as you want, fundamentally motivation comes from within. Until you figure out why you're sabotaging your hard work and your health, your junk food binges are likely to continue.
Just my opinion, of course. Kim
