The type of people who consume energy drinks on a daily basis have much bigger things to worry about than stained teeth and gum cancer.
GATORADE: LIMON PEPINO FLAVORapparently lime cucumber is a thing for the mexicans, so much so that Gatorade mass produces a flavor of their beverage for this market segment. While not an energy drink in the traditional sense, this stuff tastes so awful it will perk you up right from the first sip. In addition, unlike most energy drinks and stimulants which quickly succumb to tolerance, every sip is more repugnant than the last. If you manage to choke down the whole bottle (which I came nowhere near doing) you will be filled with the energy of a migrant laborer working for each of the $3 per hour he gets to harvest crops under a brutal foreign sun.
