I don't understand the demonisation of coffee. It has a lot of health benefits. Too much is bad of course but so are most things in excess.
Reliance on it is a different issue.
I think as soon as it's a habit you are reliant on it. That doesn't sit comfortably with me, that I have to have a coffee each day or I struggle.
There are health benefits but I'd say the majority aren't drinking it for that reason. Caffeine is a very strong habit enforcer.
