As if I needed another reason to drink coffee.
It’s ok, me too. At home I’m a 4-6 cup a day drinker. On the go 2-3 Starbucks. I have a serious problem.
Even non-psychiatric drugs like NSAIDs, insulin, hypertension medication, etc. can have a withdrawal effect.
I might be mistaken, but I am under the impression that addiction is psychological in nature. Take gambling addiction, for example, I am not certain if there is any physical withdrawal effect, but there is definitely a psychological compulsion.
