I feel the same way. I used to do that too. Basically what I do is just eat whatever I want and I won't get on the scales until I am TOTALLY disgusted with myself. By that time, I've gained tons of weight. I'm good at denial.
How is PP going for you? Are you finding it hard to follow? I'm still not feeling 100% comfortable that I know what I'm doing with it. I plan on starting it next week tho. Today is my 12th day on Atkins Induction. I lost 5 lbs. in 3 or 4 days. Then I gained a few because of my time of the month. It took me a few days to take that off. I've lost 6 lbs. so far. I have the feeling I'll stall here because that's been my pattern.
I'm going away this coming weekend and am going to try my best not to cheat.
