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.
You sound like a puritanical bore.
I’m puritanical because I prefer the things I consume to not harm me if I stop taking them? Like today I went to an indoor water park and had some lovely shrimp salad.
Those two are wonderful because if I choose not to go swimming tomorrow (hard to go every day during the winter) I will not have a variety of physical negative side effects. I also don’t have to eat more shrimp or risk a mental break down.
