The people who say they need 3 cups of black coffee to start their day are just addicts with a high tolerance that experience mild withdrawal symptoms each morning.
If you feel like that, it’s your body crying for you to take a break.
If you like an occasional cup of coffee or energy drink to get through something, then that’s fine. But if you ever feel like one isn’t working like it used to, you should take a break from caffeine to reset your tolerance, not up the dosage like an addict.
I like coffee. It tastes good. I like the way a small dose of caffeine makes me feel at different points in the day. I feel focused and alert. I enjoy a nice espresso after a big meal and a few glasses of wine. I like sipping a warm cup of tea or a latte while watching the birds from my window in the morning.
Caffeine is a drug. In moderation, there’s nothing wrong with drugs. I agree there are probably too many people addicted, and too many people abusing caffeine, but I would argue that it’s not because of coffee. Most commercially available coffee doesn’t really have that much caffeine in it. You have to make it at home fresh if you want the high-test stuff.
