This one time, at band camp...
It was my freshman year. We were a percussion ensemble, and were about to face six hours of torturous harnesses on our own time. My band director decided to pep us all up by making us chug a half pint of Dr Pepper, a drink he doesn't particularly love but obsesses over because it shares its name with his wife. I hadn't tried any non-lemon lime soda since childhood, when I was overwhelmed by the fizz, so I was amazed at the sweetness. I've been drinking it ever since, except when I was in the hospital because albuterol.
