I've never seen reliable data suggesting that sucralose is harmful. Could be wrong. If you wouldn't mind giving sources, that would be helpful. Or is it just a personal sensitivity? Don't mean to pry. I'm just curious about the issue.

It just tastes disgusting to me and ruins anything it's in. I have a long history of avoiding certain foods/ingredients (e.g. onions) so I was already somewhat used to reading ingredient labels before deciding if I should consume things and being a bit picky generally.

From another angle, I think it's quite shady and dishonest of them to mix artificial sweeteners into non-diet drinks and not make it clear. If someone sells sugar free drinks and not-sugar-free drinks, they shouldn't both have sucralose.

I have heard certain artificial sweeteners kill your gut bacteria, but honestly I don't care much about that. If I heard that about sugar, I wouldn't start avoiding sugar.
