"I didn't enjoy my lunch, so a handful of peanut m&m's won't hurt."
"I had a bad day at work so I deserve that glass of wine/cupcake/Taco Bell Mexican Pizza."

I can also identify with the vacation excuse. Man, in June I ate and drank to my heart's content while on vacation and managed to only gain 1 pound. However, it took me FIVE WEEKS to remove that 1 pound! So I definitely don't fool myself, because I know that everything counts! And even when I've had a really really bad day, I still enter all the calories in fit day for a dose of reality. Helps me do better the next day.

I totally understand this! I still have problems with cake because I think, "I can have one piece", but then I think, "I don't want one piece, I want a CAKE". And I also happen to love pink, so I get it. Making peace with the 'small' is a tough one, but I know you'll get there.

Or, get that big cake and throw yourself an equally big party so that it will be demolished by the time it's over! That would negate the 'all yours' part, I know, but it's a step in the right direction in controlling your food. If I want to get rid of baked goods, all I have to do is bring them to work and wait a few minutes.
