Agreed that HFCS is not only bad for you, and doesn’t taste as good as sugar.
I prefer sweet tea with real sugar.
However, in restaurants that only sell unsweetened tea, I use Splenda, because it’s damn near impossible to dissolve sugar in ice cold tea.
I think the reason some places sell it presweetened is partially due to that - it’s difficult to get the sugar to dissolve once it’s cold.
Which is why I never drank tea as sweet as that served in the southeast. The only way I will drink presweetened iced tea is if I dilute it with some unsweetened tea till it has about the sweetness I used to drink before I was a teenager. I normally drink about half a gallon to a gallon of unsweetened iced tea a day during the summer. I do put lemmons or limes (preferably limes) in it.
