Drinker

I drink coffee occasionally all this while,
I am not a super fan of coffee that I will need to drink at least 1 cup of coffee per day,
I drink it only when I want to.
This phenomenon has changed since the day I started working,
I still drink coffee when I want to and I limit myself to only 1 cup of coffee per day,
the changes is that the frequency of drinking coffee has been significantly increased.
I might drink coffee once a month last time,
but I drink coffee at least once a week now.
Not that I have become a fan of coffee (or what so ever),
but making myself a cup of coffee has become something I will do automatically.
I have greater urge in drinking coffee and I will just walk myself to the pantry for coffee.
Still,
I can't take the bitterness of coffee,
and bitterness of coffee is always the reason why I can't be a fan of it.
Then why am I drinking coffee?
Why do I have increase frequency of drinking coffee?
The answers might probably be the same as smokers,
some sort of unconscious addiction that we can't seem to get rid of it.
