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.
Eh, I don’t think the two things have to be tied. I consider myself a coffee person, however I also typically have only one cup of coffee a day (and some days not at all.) I don’t drink caffeine habitually otherwise, with perhaps one soda a week, or maybe a pot of tea on occasion (which is sometimes caffeinated) when I’m in a cozy mood.
But that one cup in the morning is important to me because I love the taste and smell of coffee. It’s part of my morning routine and I enjoy it. If something happens and I get distracted and don’t have that cup it’s not the end of the world, and I only usually notice when I end work for the day and go to clean my desk off and the cup isn’t there. For me it’s not a caffeine addiction so much as a morning treat. To be honest if they made a decaf version of my favorite coffee I’d buy that instead - I’m just here for the flavor :)
