In my experience, frequent cheats = falling off the wagon completely and only hopping back on after a 15-20 lb gain. If you're going to cheat, I find its best to plan them well in advance. It gives you time to look forward to them, and will help keep you from going overboard. I'm allowing myself 1 alcoholic drink on Super Bowl Sunday, for example. Planning your cheats a month in advance keeps you in control... It's the impulse splurges (let's go get carry-out tonight) that get you in trouble and can send you out of control.
I agree, a good solid 2 week Ph1 is important after any cheat. Purge the body of toxins and cravings, and you'll be far more successful. Good luck to you!!!
