First off, 23lb is GREAT! While some people here lose more during their first month, it's often because they have a greater amount of weight to lose until reaching goal. Your journey is your own, and comparing yourself to others is only going to bring you down. After all, when in your life have you lost 23lb in a month and KEPT it off?
To address the cheat eating: STOP IT RIGHT NOW. You're fairly well healed at this point, but if you're not cleared for all foods, a stray piece of crunchy chip could irritate your staple line and make you VERY physically ill.
You will never have the amount of willpower and restriction that you have right now. It is entirely on your head to follow the rules, build good habits, and maximize the loss during your honeymoon phase.
Get the BBQ chips out of your house completely. Don't even let yourself be tempted by things you shouldn't eat. If it's not in your pantry, it can't tempt you!
You can get back on track and keep going, I have faith in you!

The real question is: why are you eating those things? What is prompting you to eat? If you feel like you can't control it, absolutely find more support.
Everyone makes mistakes, by the way. I have made so many mistakes I am surprised to have made the progress I did. The wonderful thing about what you are doing is that you are taking a hard look at your habits and are willing to change.
Guilt and shame are trying to tell us something, and it behooves us to listen. We need to open ourselves to these feelings and ask them what they are saying. Do not drown in it, but use it as a clue and motivation to move forward.
Stand up and keep going forward 
I follow a ketogenic diet post-op. I also have a diagnosis of binge eating disorder. Feel free to ask me about either!
It is not that we have so little time but that we lose so much...the life we receive is not short but we make it so; we are not ill provided but use what we have wastefully. -- Seneca, On the Shortness of Life
If you aren't working with a therapist I would ask for a referral. IMHO the most important work we can do post-op is above the neck. Guilt and shame are pointless... better use of thoughts would be figuring out a plan for next time. Maybe chips just need to be out of your radar for a while... so not in the house, at the other end of the table at a restaurant. Is it social situations only? Habit? Triggered by stress? Boredom? etc... and then create your plan for next time.
P.S. 23 lbs is above average BTW
