One of the reasons I overeat is instead of SI in some other form. So I control one set of urges by giving in to another.

There are other reasons too, I don't differentiate between different feelings very well, so if I'm anxious or bored or angry or tired or lonely what I think I'm feeling is hunger and will eat. Plus there is that surge of "happy" that follows eating and sometimes I just need that rush.

Mostly, now, I've been overeating for so long, I don't even register that I'm eating at all. Today has been a good day though as I've only eaten at mealtimes (hurrah).
