Have you looked into AVRT and or the Rational Recovery wesite? I cheked out that site my first day here, there is a free crash course on that page, really helped me with urges/cravings/feelings of weakness , couldn't hurt.
Great idea to post here and get it out there that you need some support and most willing audience around right here.
You got this , don't let the other you(AV) talk you out of it. Thoughts are not action, thoughts can be dismissed .
The first week is brutal , but to get through it, you have to get through it.
On the more practical side , the Golden Corral eat to busting thing has a ring to it!
