Welcome!
I'm Kristen, also 5'2", also around 220 and live in Brooklyn. Definitely sign-up to go to the seminar @ NYU. It's a great, low-pressure environment where they give you quite a bit of information about the surgery, their practice, the long term results, insurance company requirements and obesity in general.
I'm about 1/2 way through the process now -- I've been to the seminar, gotten my psych consult and been through my physical with my PCP. My next step is to meet with NYU's nutritionist, NP and do my surgical consult. (All happening on 7/7).
