Good for you! Several years back my team at work used to joke about my caffeine intake... it was just a compulsion that when my cup was empty I'd get more coffee. I found that the beneficial effects plateaued around cup four every day, and beyond that it was pure habit (I'd get the crashes later in the day but more caffeine wouldn't help much). I was down to about 2 cups a day at work, but now that I'm home all the time, I'm back up to four. It's just... comforting to have in my hand.
