I don’t think I’ve ever been addicted to tea or coffee - but I have found it is quite easy to get into (and out of) a habit of drinking coffee or tea.
I used to drink coffee quite often when I worked in an office with a coffee machine - then when I retired, my part-time work took me to an office where drinking tea was “the norm”
Now I’m fully retired, I seem to have lost the habit of tea and coffee drinking - I may order coffee if I am in a cafe or restaurant and I have a machine for making fresh coffee at home but I only tend to use it when I have visitors.
I sometimes make a mug of Yorkshire tea at home if I fancy one but most of the time I prefer to drink tap water at home - or if the sun’s over the YardArm, I plump for Alcohol!
