I wouldn't believe a word the guy says. He just want to be high.
As for the weight....the surgeries are an absolute last resort and bullshit for any other reason. How hard is it to do 30 minutes of light exercise a few times a week, and eat a little less. Even if he still ate the same, he'd lose some weight. Guy's the biggest baby in the world. Waaaaa. It's only cause he makes a lot of money that he gets away with this jive.
