I’ve had a similar experience, before if I ate anything that I felt I shouldn’t have, I would have been the same and I would have said to myself “well, I’ve already blown it so I may as well just carry on eating”, but now I don’t have to do that. If I eat too much or make an unhealthy choice I can stop it and make the choice not to carry on eating. It really helps me to remind myself when I am overeating that I do have a choice. When I remember this, I don’t feel the need to rebel and eat everything as it is always there if I want it. This has been a huge help for me too.
