Right after the birth of my daughter (who is now 2 and 1/2) I started to purge. Not all the time, only when I had induced alot of carbs or calories (pizza, ice-cream), in one sitting. Surprising since I was 30. I don't binge and purge, and it's not constant, but when I eat alot, I sit and obsess, until I eventually do get rid of it. I think it's just a control thing, that I am afraid of gaining weight, (I was on lithium for bp and finally lost the weight when I changed meds) and liked the reaction I got.
