Girl, that is not good!! I don't know how you could eat that much five days post surgery after what I'm reading. If you're doing that now, I'm worried about your future success. You might want to see a psychologist to help figure out what drives you to eat.
I have been thinking about surgery for 15 years but would never do the bypass. I backed out of the sleeve 2 years ago after meeting with the surgeon. I'm starting the process again to get the sleeve and I'm still scared. I plan on seeing a psychologist pre and post surgery to help me with what drives my food addiction.
As people say, this is a tool, not a cure. It's still up to you to make it successful. I know a lot of people that have gained all of their weight back post surgery.
I wish you the best on your journey.
