I don't know for certain, but it seems like this is a normal reaction. Although I've not started pigging out, when I do eat, I can't help but think..."better enjoy this now cause in a month and half you won't be able to touch this stuff". But I've wondered if I'll start pigging out. But the thought of having to lose that much more weight is enough to deter me. The sheer excitement of the thought of having the surgery and actually feeling full with so little is enough motivation. Don't get me wrong...I LOVE food. I'm not an emotional or binge eater...I just love the taste and can't even fathom leaving over half of a meal on my plate! Just think of the benefits of the surgery and don't let the junk food rule you. Use these next few weeks to mentally prepare yourself, cause if you can start now it will only be that much easier once the band is in.
Although you'll be post op by then...my pre-op liquid diet is set to begin Dec. 24th. Just think, knowing you can technically still eat a lot on one of the biggest food holidays and not doing it! Oh my. I'm already preparing myself. In a way I just look at it as if I can get through that, that's an excellent start to this journey and I can prove to myself it's just food. I'll be ok without it.
Best of luck to you!
