I started drinking coffee to help my insomnia - to wake up for work that morning after a night of constant tossing and turning. I got the insomnia solved, but now am addicted to my coffee.
At first I did notice it helped open my lungs, but not so much any more. Although with that said, my lungs are worse overall than when I first began drinking coffee.
I was up to a half a pot of coffee a day (6 cups)...but I have cut that in half because it was so dehydrating. In fact now, I notice how dry my hands are if I drink more than the norm in one day.
I too have two coffee makers, a coffee grinder, too-numerous-to-count coffee cups, and only drink Starbucks (btw, they have TWICE the caffiene of other coffees (wink). )
Best wishes with your addiction....<img src="i/expressions/face-icon-small-tongue.gif" border="0">
