Yup. And there might be some emotional times when you find yourself in situations where you would normally indulge that, and get the resulting pleasure, but now you can't and so emotionally, you're at sea.
I found myself in tears on kings cross station a few weeks on, cos I couldn't have something from the Upper Crust. It was such a hard wired association for me: secretive opportunities for extra food when out and about. A way of treating, or pleasuring (!) myself that played hell with my emotional coping strategies when I was denied it.
