Same with me. I am somewhat amazed when I remember the kind (and quantity) of junk I used to be able to gobble down, especially considering the fact that I am/was) a binger. Now if I do the same, I suspect I'll just make myself sick, and I mean the real sick, not 'just a little uncomfortable'.
I decided it was a good thing. My body doesn't need junk anyway, and is now smart enough to recognize it. Good body, good.
