Hi, I'm not an advanced member but why are you going back to eat again after 1 hour? Try drinking water or taking a walk...the surgery is only a tool and we have to do our part...we are all here because we have a problem with FOOD either overeating/binge eating, stress eating, emotional eating or whatever the case may be.
Of course eventually if you keep overeating and then throwing up and going back for more food you will indeed ruin your tool...I suggest getting help from a therapist because it seems like you are slipping back into bad habits...We HAVE to learn to "Eat to live and not Live to eat"
We all want you to succeed but you have to do your part like you did in the beginning. You lost weight before so you can do it again. Get some help and take care of yourself.
I wish you all the best and we are here for you. ((Hugs))
