I had surgery on 1/15/13. Everything seemed to be going great, weight loss of 15lbs right away. Now it's been 12 days and I haven't lost anything. This is very discourging Not sure if this has happened to anyone else so early in the game? Also, I was wondering if anyone gets dizzy and heart races when standing from a sitting or laying position? I'm thinking it might be dehydration, and I try very hard to get all my fluids in, which is pretty much impossible right now. Thanks for any feed back
