I have been instrumental in banning bottled water on the set. It hasn't gone that well with the crew... so I replaced it with tequila.
People have this obsession. They want you to be like you were in 1969. They want you to, because otherwise their youth goes with you. It's very selfish, but it's understandable.
I listen to my body, I give it things it wants and I eliminate things it doesn't want.
