The stats say it has greatly decreased sugar consumption in soft drinks. From my point-of-view (someone who rarely drinks soft drinks) it seems that most soft drinks now mix artificial sweeteners and sugar, so effectively all soft drinks are now "diet" varieties.
It's really annoying. I also drink soft drinks very rarely but if I want, say, tonic water that doesn't taste like crap I need to splash out on a premium product. Other things (e.g. cranberry juice drink) are simply unavailable without artificial sweetener. Reduced salt snacks are also shite. It is hard to find a treat that is still actually a treat.
Sizes tend to be a lot smaller. One poster above said a large soda in the USA is almost one litre! In the UK it's roughly half that size at 500ml.
As the sugar level is directly proportionate to the overall volume, it can be quite surprising how much sugar there is when you aren't used to such massive servings.

There are two sizes of single-serving sodas sold commercially in the US.
A small one, a can, is 12 oz, 355 mL.
A large one is 20 oz, 591 mL.
To buy a 32-ounce soda, you'd have to do something very strange.
(There is another common commercial size, the two liter bottle of exactly 2000 mL. Those aren't intended to be bought and drunk; they're intended to be bought, taken home, and stored in your refrigerator over time.)
A gas station? No, they'd be selling prepackaged sodas in the 20-oz size.
You might be able to do it at a 7-11, since they sell empty cups that you're meant to fill with a slurpee. I don't know if they also have soda fountains to fill those cups.
