I got some of these a while ago. They were ok, nothing special.
I myself prefer Bawls while gaming, g33k b33r specifically. Mainly for the jokes.
Heh. Heh. Bawls.
When you play D&D you drink Coke, period.
The Church is currently divided about indulgences for diabetic players that drink Coke Zero, the IV Council of Palanthus will probably fail in favor in the next few months, Diet Coke of course has been declared anathema.
As a diabetic gamer, I was saddened that only one of the flavors in the D&D pack was sugar-free. At least it was moderately tasty (a friend brought a case of the D&D variety pack to a recent session).
I drink Diet Coke while gaming (see above), with Captain Morgan mixed in once we get to the evening, and an occasional sugar-free Red Bull if I get really tired.
Heretic!, Heathen!.
I drink “something dwarven, anything that’d make an elf roll a fortitude save”
I hate Coke and most caffeinated sodas.
But if you drink something dwarven you’ll prolly end up doing something drunk.
Alcohol and RPGs dont mix well in my experience.
You may take up that bit of dogmatic debate with my pancreas, and my endocrinologist. 
With the wrong player, agreed (and I’ve had a few of those). In my main current group, where we’re all responsible adults who aren’t likely to overindulge during the game, it works out just fine.
So, with the feeble excuse of “not dying” you refuse to accept the blood of our savior (Gary Gigax PBUH).
I find your lack of faith… disturbing.
At least you could try the insipid Coke Zero instead of that swill…
I’m part Dwarf, so it doesn’t affect me like you think it would. 
Most of the D&D I’ve played has been accompanied by RC and Dr Pepper. But for my birthday this year, my mom sent me some teas that would work well, too: A box each of Hobbiton Meadow Mint, Bilbo Baggins Breakfast, and Gandalf the Grey blend.
