Hi, my name is Kelly i am 27 yrs old from long island NY, my Dr. Vorha. I am planning on getting the gastric sleeve done. I have done all the requirements the office has asked me to do. At my last appointment the lady told me at my next appointment which is may 13 i will start the opti-fast which is used as the liquid diet to shank my liver and they are pushing for a june surgery. I am a little nervous but i have done my research and have read a lot of posts from others to better understand what i will be going through. If there is any tips anyone can give me about pre-op or even post-op it would be nice.
