Mountain Poison?

Ignore Obesity, that is a retarded statement in the first place. Any soda can do that.

Sperm Count thing is in constant doses, iirc. Like, 2 cans a day for a year.

Memory Loss is difficult to prove, so that may be a difficult thing to include as well.

Blue skin is lulz, never heard that before.

Burning holes in stomach is an... interesting statement, considering there's acid in it. Maybe an ulzer? Whatever it's called.

Putting you into a coma is a thing with any drink that's made to give energy through a drug. Monsters can have the same effect.

For you to have viable evidence, you're going to need to tie all those things to the ingredients in the soda, and reference studies which have found results that agree with your stance. Unfortunately I don't know anything about what's in it other than the standard for sodas.

It can definitely contribute to obesity though. Coma would probably be related to the sugar and caffeine content, which while high even when compared to other sodas, is probably not high enough to be coma-inducing as long as you don't drink an absurd amount. I've never heard about burning holes in your stomach. For that to happen there would probably have to be an extremely powerful acid in it since the stomach can handle its own acids fine without burning itself. I believe the stomach acids are around a 3 or 4 on the pH scale, while the acid in soda is closer to the 5-ish range I believe.

Sperm count seems more like an urban myth. I've heard it's a particular food coloring in the soda, but honestly if it's true, the actual decrease is probably insignificant and won't make you anywhere near sterile or have the effect of contraception. I've also heard caffeine has the same effect.

Skin turning blue is something I've never heard before, and quite honestly I don't know what to make of it.

I like to think of Mountain Dew as the energy drink of the soda world, except it gives you no energy that you can actually use well and is much less healthy for you.
