I'm from Knoxville. Dr Boyce from New Life Center performed my sleevectomy January 13th 2015. I'm almost a year out and down over 180LBS. Though there have been a few rough patches(Mostly emotional/No physical complications), all in all everything has gone very smoothly and I'm extremely satisfied with my decision to have surgery.
According to my surgeon and the research I've done on the gastric sleeve procedure, ghrelin levels are only reduced temporarily. The body is always striving for what it considers homeostasis and eventually begins to compensate for ghrelin reduction. It may take a good while for this to occur but it appears to be the rule for most, rather than the exception.
