I eat relatively healthily, and don't binge, and the only thing i do binge on really is alcohol, but even then i only drink on a night out.

I very rarely throw up, maybe once a week/fortnight, but when i realise that i have eaten/drunk a little bit too much i feel horrible, and try to throw up. I have to say i am not very good at it because maybe one in two times i actually manage to.

The only other time i would do it is if i was on a night out and i got upset about something (usually arguments between friends) then i deliberately make myself throw up. i tell myself that it is to sober me up a bit (even if i'm not drunk), but i'm think i'm just lying to myself.

does this mean i have bulimia, even if i very rarely throw up. and if i don't whats wrong with me?
