t: non-addictive coffee addiction

I am one of those addicts too.
some days it goes up to 4 glasses.
I'm happy no problem, the head is getting vigorous.
it does not affect my sleep since I have been drinking like this for years.
I have three types of coffee machines at home.
yes i am addicted

It is the situation that I support by drinking 3 thermos coffee a day.

Well, drinking normal coffee, what's wrong with this.
not an extreme event to open a thread

imagine a vegetable carving cutting through your esophagus starting from your throat, up and down, and continuously; If it becomes a habit, it does exactly that. (see reflux )
