Why diet soda? I mean I understand if someone has a health condition and cannot consume the sugar in regular soda, but otherwise I hear the false sweetener can be way worse for you health wise so if you don't 'have' to drink diet soda why do you?

Just can't understand because I find it to taste bad and make me nauseous so I don't see why anyone would want to drink diet soda. I personally think if I had a health condition that disallowed me from having regular soda I just wouldn't drink it at all anymore.
