I was hoping to wake up to some Orrex type of headlines in the news this morning.

IOW, prescription meth.... He always takes the stuff when he speaks...

to recover from a combination of the drugs and overexertion for his unhealthy condition.

There's an scene where he collapses in the passageway to the stage on his way to do a show. Colonel Parker (who you'll hate by the end of the movie) says "The only thing that's important is that man is on stage in 10 minutes."! The doc shoots him full of something, and the next scene is Elvis on stage jumping and gyrating.
My guess is whatever that shit they were using on Elvis was, it's probably a real close relative of what they use on that idiot whenever he's got to, you know, function as a human

I have known for years what a lying, thieving, manipulative pos he was. If Elvis had had a legitimate manager, there is no telling what he could have accomplished. He wanted to be a serious actor, for one thing. Showed up on set first day of his first movie with the entire script memorized.

It's probably the same shit they've been pumping into Moscow Mitch for years. No way in hell these walking corpses would still be kicking without pharmaceutical intervention!
