Alexiel, you really don't want to learn to purge. There are alternatives, you know...

First off, your T is absolutely correct -- and an utter idiot when it comes to disordered eating. Ignore him, and don't let that sort of attitude anywhere near you. It won't help you a bit.

Second, are you on any other medications? Any psych drugs, that is? My bet is "yes" -- in which case you want to wander over to your doctor and start talking about medications to help you with this problem, like Topamax. Many psych drugs can trigger overeating, and the Topamax helps a lot to control it.

And, if your doctor isn't aware of this use of Topamax, go find one who is. Life is too damn short to waste time with a doctor who can't meet your needs.

Good luck.
