Most days, I start the day with two large (10 oz) mugs of fresh ground drip brewed coffee. Some days, I make three. It isn't dark roast (French Roast, etc.), but it's seriously strong.
I call it "every other day" coffee because it'll put hair on your chest, and if you already have hair on your chest, it'll make it fall out. That tells you if it's an odd or even day.
OTOH, if I drink coffee after about two in the afternoon, I'll wake up about three in the morning and be pissed at myself for having done it.
