IMO I think the drugs KE was giving her helped and I wonder if the medical thing Doctor Levy was treating her for had to do with stomach stapling.
I've thought of her having had the stomach stapling as well.
Heh heh - Dr Levy was on a TV tab the other day and the voiceover said that, of course, he couldn't divulge what he treated ANS for, but it had something to do with facial line fillers ...
