Hi, Lockitup, I recognize you!!
Well, what you are describing (and I'm not a doctor, but I'm a know-it-all
) would be considered an ED-NOS, because you are purging normal amounts of food and not bingeing. This is eating disorder behavior. Get help with it now before it gets out of control. I started like you as well, just throwing up normal meals, and then it quickly led to bingeing, which quickly led to gaining over 100 pounds. Bulimia teaches you to binge eat. If I hadn't started throwing up, I never would have fell into a bingeing habit.
So try to stop right now, and talk to a professional if you can't quit on you own.
