I “discovered” caffeine the summer between 7th and 8th grade. Vanilla lattes changed everything. In high school they sold us sodas and snacks between classes. By 9th grade, I couldn’t stay awake through 2nd period (geometry) without drinking a 20 oz. Mt. Dew before class. When I realized what was happening I stopped drinking Mt. Dew. It was a rough couple of weeks. It was my first experience with drug dependence. Informed my approach to drugs for the rest of my life. I got lucky, I suppose.
