I really disliked their diet flavors, and most of the non-diet ones. I managed to find a great rootbeer syrup from someone else, but it still had sugar. Now, I usually either go for an energy drink syrup if I want caffeine (Mio or Power Ade have some good ones) or Koolaid liquid for no-sugar no-caffeine. I make them much stronger than my wife likes, but that's just another feature... You can customize the taste a lot. Losing your favorite flavors sucks, but the silver lining is that it pushed me to look for other flavors, and I definitely found some that I liked.
