I put "cups" in quotes because i think when they do cups of coffee in studies they mean 6-8 ounces while my cup is probably closer to 16-20 ounces.
I had gotten pretty good about my coffee consumption while I was telecommuting from home. Previously at work it had gotten to like 3-4 "cups" a day and then I'd get those "haven't had coffee" headaches on days I'd miss a cup.
"And for crying out loud. Don't go into the pain cave. I can't stress this enough. Your Totem Animal won't be in there to help you. You'll be on your own. The Pain Cave is for cowards.
Pain is your companion, don't go hide from it."
