Are you inducing vomiting? Are you overeating prior to vomiting?
I think you need a new doctor!
I am bulemic (or a compulsive overeater) technically - I don't induce vomitting but I starve myself for periods of time and then binge for other periods of time and that is also one of the definitions of bulemia.
I am 15 months in recovery, which I achieved through a treatment centre for 5 weeks and 14 months of 3 overeaters annomyous meetings a week. It's a lot of work but it's worth it, I actually have more time to live my life now because my eating was stealing way more than 6 hours a week from me.
