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 love coffee and recently had to go to one cup when I wake up and then no other caffeine for the day as part of working through a sleep disorder.
It’s been really, really beneficial for my mental health. I am sleeping better, interrupting less, and generally have more appropriate appetite for food (I have issues with late night eating that are essentially gone).
I didn’t want to do this but it’s been pretty good.
I still enjoy a decaf Americano every so often in the afternoon.
