Oof. I remember that powdered iced-tea... shudder.
Artificial flavor, artificial color, artificial sweetener. I was addicted through high school, college, and beyond. I’d make it double strength back in college. Around the time I was expecting Bill, 1993-4, my digestion went wonky and I started drinking room-temperature Diet Coke instead. Eventually I developed a taste for coffee, and only have iced tea now when we’re eating out, although I still drink hot tea in the winter sometimes.
