I really love Mountain Dew, its my fave, I drink it whenever I can, Do you like Mountain Dew? 
I like it ok.  I like it more than Mello Yello, but less than a lot of darker sodas.
Yeah thats why I generally stick to the dew because its lighter than dark colas like Pepsi. They say Mountain Dew really isnt too healthy though. Do you know what they put in it? 
Sugar is all I know for sure.  The formula for the drink is kept secret, though it's changed a few times, most recently in 1961.
Oh really? Well I seen on the label that they put brominated vegetable oil in it, DO you have any clue what that is? 
I think it's mostly used to keep the elements in soda from separating while it's being distributed.
Oh ok, I heard a lot of bad things but I dont care, I only drink like 2 cans a day, Thats not too bad right? 
Probably not.  If you're really worried, you can always try switching to Diet Mountain Dew, though it's not completely proven to be overall healthy.
