Earlier quoted context omitted.
I'll second this. I don't even drink coffee. I've encountered people who seem absolutely incredulous that I take no stimulants at all. "How do you stay awake?" is something I'm asked. My go-to response now is "I don't. If I'm tired, I get more sleep." Some of these people probably think that I'm lying. There are a lot of people who think that sleeping at work is a bad idea, but I think it's a lot better than guzzling…
As a corollary to the OP, it seems like the people who deliberately don't take stimulants _also_ love talking about themselves and how it's a superior lifestyle. :) Not saying you're wrong, but the sanctimony from both sides can be a little exhausting is all.
Also, the terminology is arbitrary. Water can surely create endorphin when you are really thirsty. Toxins are problematic, but even water is toxic in high quantities. What's really toxic is dogmatism ... and narcotics that numb senses, which is the opposite of stimulation if you think about it. Only, it's not black and white like that, if the body is stimulated to feel less.
Anyhow it's pretty simple to see which side f the equation is the extreme negative. Fiding the middle is difficult and hence dangerous.
