What an articulate and succinct way to put it, Antiaris. I never once assumed I had started a "new disorder" but perhaps was worried such a thing might develop as such.
In some ways I think it started as a "screw you, ED!" - which then got a bit out of hand, and for lack of a better way of putting it, I was enveloped in this... bubble of helplessness as my mind didn't connect the dots. I just continued to eat even though I didn't recognise any feeling of satiation or hunger; I just ate.
But the fact that I had about <2400 kcals on Christmas day and then perhaps 4500 the following day, that's a mere two days out of my ENTIRE LIFE I've overeaten; yesterday I went back to my standard 2000, but regardless, the aftermath shown on the scales.
What I cannot fathom however is that the day after my "binge" I as only up one half of a pound, whereas the following day (today) I've gained nearly 4lbs.
It makes it evident how people easily put on stones and stones with consistent overeating...
