NEED TO HEAR FROM THE POST-OP PEOPLE

First, you have several months to get  better understanding of what WLS is all about.  I suggest that you continue to research the general subject of weight loss so you can get a better sense of where you are. 

Fact: at this point in time, only 3-5% of people who lose weight keep it off long term.  So, I don't know if the anger at yourself for not getting your **** together is justified (not that I didn't feel that way for 50 years while I suffered under the delusion that I was one of those luck 3-5% of people).  I felt I would never be one of those people who had surgery - what a fool I was for waiting so long. 

You may also come to see that food has no enchantment - and that corn dog will not make your life better.  It can be better to work through some of these issues before surgery to reduce the chance of buyer's remorse.

Good luck on your weight loss journey - where ever it takes you.
