I've never been a fan of coffee, but I liked drinking it, but more out of habit than desire, and always at work (rarely at home). Years ago I started to notice terrible headaches on the weekends, and only after a long time did I manage to understand that coffee withdrawal was the cause. For me the conclusion was obvious: I will no longer take something that affects my body at this level. I have the same problem with Coke/Pepsi, I stopped taking it too.

Fun fact: on the same day I noticed and stopped taking it coffee, 5 days later I had terrible muscle pain in my lower back (I could hardly sleep). 2 days later I had no more pain. I researched later and saw that this type of pain could also be caused as an effect of caffeine withdrawal.
