well i recently discovered ED's I like them in the morning instead of coffee now.
I have become a monster regular (and yet trying other flavors). While a friend of mine in the past 6 months picked up red bull and swapped over to full throttle (he likes the blue one). While yet another has been telling me to try NOS. I like my energy drinks and prefer them to coffee now. I drink one a day. I dont see them going anywhere.
