Good luck CK. I told myself that I could just stop too... too many times to count. I was also bulimic for years and stopped, only to replace it with another coping mechanism, drinking.
Perhaps you are in control and can just stop. If not, and if SR and forums like it aren't for you, perhaps you could try personal therapy if you find yourself drinking again. Just don't do what I did and lie about your drinking though (to a therapist or yourself). I wish you all the best.
