If you still drink caffeine regularly and started early you will not have any memory of your system pre-caffeine, so you may find it hard to assess if there are any ill effects. It is widely drunk, but also widely implicated in lots of negative physical and mental responses.
I personally haven't drunk caffeinated coffee for almost 25yrs, as I have a longstanding health condition and was told that I'd benefit from avoiding it. I will add that my previous consumption of caffeine had nothing to do with the onset of this health condition, it's just not helpful to consume it now I have it.
I don't miss caffeine at all, but as I said, back in the 70s, we were drinking coffee and my kids were in the 90s.
It should also be remembered that tea has caffeine too, and everyone I knew growing up and when my kids were young, all gave their kids a cup of tea, even now, I see very young kids with a bottle or sippy cup containing tea.
Yes, there's likely more caffeine in coffee than tea, but it's still there.
Maybe, the coffee and tea producers should change their production fully to decaffeinated, then no-one would be getting 'hooked' on it.
