When one is extremely sluggish and unable to think about anything but coffee. Timing varies, but it is often reported to be particularly intense at 6 am, 9:30 am and 3:30 pm.
Oh man, my Caffeine Deficit Disorder (CDD) is totally kicking in, if I don't get some coffee soon this hole day will be a waste of breath.
