It's been maybe 15 years or so since I've had a glass of Coke or Pepsi or Dr. Pepper or 7-Up or Sprite or most other sodas. The only one I can really summon a taste-memory of anymore is Dr. Pepper and 7-Up/Sprite. I can't even remember what Coke or Pepsi tasted like.
I've had root beer more recently, but only in the form of A&W rootbeer floats. And I've occasionally had one of the mostly-fruit-juice carbonated drinks.
I stopped drinking them because I couldn't have them anymore. I can't have nutrasweet and I couldn't have sugar. I can now have them, if I want, thanks to being in pretty much the best health I've ever been in in my life. But I really don't crave them... so it's just not worth bothering with. There are much more fun ways to eat a few hundred extra calories than soft drinks.
