SURGE Disappeared While Zee Wasn't Watching
Unfortunately, SaveSURGE.org was the source who informed Zee that SURGE was no longer being sold:

I was just telling my friend about a recipe that I'll never forget, then I realized I hadn't had Surge in a while, which was one of the ingredients and haven't recalled seeing it in a while. That's how I found your site. Now I'm severely disappointed and just hoping the Surge recipes themselves are just as promising. Because one evening, when my friend and I were staying up until ungodly hours, and were tired, we decided to use our all time favorite soda, Surge, that I had gotten a cube of for my birthday.

We put 2 cans of Surge into a blender with 3 handfuls of ice, and put the blender on high and made, what we soon dubbed "Surgery". Because it tasted...pretty...Surge...ry. But knowing we might never have another Surgery again is extremely disappointing. I can't believe this happened when I wasn't looking! Damn!
