I'm the stage manager for a production where one of the actors need to drink a lot of cream soda on stage. He's drinking about three cans a show, and one of them he's chugging. He's now drunk 15 cans of cream soda in the past three days, and he's starting to get sick from it, and getting lethargic and such. And we have FIVE MORE SHOWS TO GO. By next Saturday, he'll have drunk approximately 35 cans of cream soda in a little under two weeks, in groups of 3 or 4 in the space of about 2 hours each group.

I'm the stage manager, and therefore concerned with actor well-being, but also (this being a high school production), I'm doubled up as the first aid (because I'm a certified nurses' aid). I'm trying to think of something that we can do so that we can counter-act this to some extent. I'm considering lots of water and salt, but I'm not sure.

He's starting to feel sick from it, he's getting lethargic and he can't concentrate as well. And he has to open the cans on stage, so we can't just use water.
