There is no green zone. I'm 2.5 years post surgery, and while the first year I never found the green zone, the second year and a half, even if I can eat during the day, I'm coughing until I throw up at night. There's no logic. Over time, it gets more and more useless. That is why there is only a year-long success rate. It's kind of a scam. I'm going at it on my own again with no fluid in the band.
