I am the same way. If I don't start eating junk, I don't have problems. If I have one cupcake the whole day is lost on binge eating sugary stuff afterwards, like yesterday. I went to an animal shelter where they had a bake sale and had vegan cupcakes and my brain always goes "oh, there's actually a vegan option?? You HAVE to try it so you don't miss your chance!" then spent all day eating ice cream afterwards.I guess there is conflict going on. I feel i should be able to enjoy just one. Yet I want it to be easy for me, and trying to enjoy just one makes it harder. I guess there is element that I perhaps don't want to commit really long term, or feel uncertain that I can.
And I love summer food, and summers are easier for me.
