I recently had the illustrous cherry coke a few times. Very tasty with a doobie. Can honestly say it increased the enjoyment of being stoned even more :-D But overall I rarely buy sodas (and even less energy drink), mostly tea, water, coffee and the occassional beer.
I tried a Birthday Cake Bang once probably about a month and a half ago and that was super weird. It tasted way too much like the name suggests and it reminded me of those futuristic sci-fi movies where the meal is like a little blob but supposed to taste like a Burger or something.
