Is it ok to drink 6 diet mountain dew sodas a day?!

Drinking six Mountain Dew sodas daily isn't a good idea. It doesn't matter if the soda is diet or not. Soda is essentially wasted calories that could be better spent eating something more appropriate like fruits or vegetables.

drinking anything not natural, milk and water.. and such isn't good for you. Even at low amounts, added up the sugar and what not isn't good for your body.

Only if your looking for a heart attack
