I religiously require it on hard days so I can function after work.
If you get off coffee completely, your energy will improve in general. Being tired has a purpose. One has to sleep right, eat right, and exercise, and yeah, struggle with tiredness often.
I have a suspicion that all types of stimulants bring about a slightly forced imbalance to our homeostasis that we have to pay for later. I'm aware this is an oversimplification since coffee has several good health benefits according to some sources I've yet to verify. Yet, it can aid in masking slight sleep deprivation. Over time, this can cascade into issues. We should seek to find solutions for optimal natural sleep-awake regulation.
I don't see issues with coffee drinking irregularly for enjoyment rather than leaning on it for sustenance and consistency.
