Better yet, try saying it after you had it done, which I did a year ago. ;~))
By way of disclosure, I am not obese or even overweight but I had apnea since my 20s after a very bad throat infection and eventual tonsillectomy (now that really hurt like hell). I tried the CPAP machine and could not sleep at all with it. The uvulopalatopharyngoplasty was not nearly as bad as having my tonsils removed, and it has helped me get a better night's rest. I think I probably still do have some apnea, but not nearly as bad as before, and no, I will not go to get another 'sleep study' to find out how much better. If this is they way it is, then so be it.
I don’t think a person has to be overweight to have sleep apnea. You’re one example.
Glad your surgery went well. Did you ever check into sinus problems like polyps etc?
