If not coffee?

I have been in a few conversations and, some of my friends advocate not to drink coffee. Their simple analogy is coffee affects our sleep and, it’s a drug worth avoiding. A few others tell me coffee intake can result in an uneven heartbeat. If you are a runner, it will have more adverse effects.

The fun part of science and ideology is that both are divided. So what is correct and what is not on our consciousness.

Sometimes what is good one might have adverse effects on another. I tried many times quitting coffee but came back in a few days. The side effects: I was sleeping way too much.

Every now and then brain says give up coffee and, the heart says fucking no and wins.

Another problem: What to drink when out with friends? Contaminated juice with overly sedated sugar syrup or green tea or milky/frothy smoothie?
