Two or three 12-ounce cans or one 20-ounce bottle per day.
That doesn't strike me as much. But:
1. Every time I am invited to dinner at someone's house, I have to bring my own. Nobody else that I know drinks it.
2. Every person I have ever met, without exception, has informed me that I shouldn't drink it because aspertame causes cancer in lab rats. Usually they say this the first time they see me with a can. I always say "Really? I had no idea! This is the first time I've ever been told this -- today!"
By the way, that's an urban legend. Aspertame does nothing to lab rats, or to humans. Your stomach breaks it down into aspartic acid, phenylalanine and methanol, which we consume all the time in organic foods such as meat and milk.
The problem is, Coke advertising overwhelmingly features attractive young ladies, trying to draw in straight men with the promise that "If you drink Coke, you'll get laid."
The only time you see guys alone are in humorous ads. Or creepy ones. The psychotic Sprite Boy was introduced in 1941 to force people to use the four-syllable "Coca-Cola" instead of their preferred "Coke."
But their knees are touching, anyway.
But during the Super Bowl, Coke broadcast a new commercial showing people of various races and religions engaging in wholesome activities while drinking Coke. Among them were gay dads teaching their daughter to bowl.
