I'm new?

I'm currently 19.  3 years ago, I never thought I'd find myself on a diet!  At 16, I was an alcoholic and was a pill popper and smoked quite a lot of pot too.  So, my parents sent me to rehab.  I'm 5'7".  When I arrived at rehab, I weighed 92 lbs.  When I left rehab, I weighed 200 lbs.  I tried dieting here and there afterward but nothing really inspired me.  I got pregnant (and married) several months ago and had a miscarriage and didn't find the motivation to start dieting again.  Now, at 280 lbs (yes, 280.. I can't believe it), I'm coming up on my 3 years sober (July 9th!), and am dieting as a gift to myself for staying sober.

My goal to start out with is 190 lbs, but ideally I'd like to be between 150-170 lbs.  I want to get to 190 as soon as I can, and then after that, I will focus on slow weight loss so that I can lose the rest over several more months and learn how to maintain better since I honestly haven't had a healthy eating style since I was maybe 9 or 10.

So yeah, I feel like I'm in an online AA meeting or something.  My hubby suggested I go to OA, but I think if I go to any more meetings (I attend and am a sponsor at a weekly AA meeting and go to bi-weekly NA meetings), the 12 steps will drive me insane.  So here I am.

welcome and good luck!
