What is an addiction many people don’t realize they have? - programming.dev

Caffeine, people think they aren’t addicted to caffeine and can stop any time but watch them be miserable and go right back when they try
I drink several cups a day but even if I don’t I still feel the same. I’m not one of those “don’t talk to me before I’ve had my coffee” -guys. I just drink it out of habit and because I like the taste. I don’t feel like it effects me in almost any way. I can even drink a cup few hours before sleep. I guess you could say it’s an addiction since I do it every day and don’t want to stop but I’d still rather just consider it a habit in my case.

I could be wrong but this sounds surprisingly like the "I don't actually need it, I can quit at any time, I just don't want to" trope.
Just put of curiosity if you switched to decaff for a month or something would you notice or feel any difference?

I'm not a coffee drinker so I don't really know what it's like. (I'll do tea every now and again but nothing daily or multiple times a day)

In my case I simply don’t see the need to quit. I don’t see it having a negative effect on my life and I don’t believe it to be particulary unhealthy either.
