I usually get up a couple of hours before my wife and, by the time she gets up, I've probably drunk about 3 pints of vey strong black coffee. You can imagine what she was confronted with when she walked, bleary eyed into the living roomcOR, YOU CERTAINLY HAVE IT A LOT WORSE THAN ME. "caps"
I do give up caffeine from time to time but, I have a strong black coffee on my desk now, palpitations aside, I do OK with it. Alcohol is key for me, dry january sent me nuts, my wife feels like it self-medicates my symptoms, my daily hangover nullifying the usual symptoms. Convenient I have to say!
