Maybe this isn't a heretical suggestion after all.  As much as Joy likes
coffee, a well documented fact, if you search the archives (smile Joy),
I am sure that "cut the caffeine" doesn't mean to go without it
altogether, but to limit / lessen the intake "if your hands and feet are
cold," as she wrote and before bed so you won't be working at a
circulatory deficit when trying to stay warm under the covers.

And, IIRC, I think that the alcohol dilutes the blood vessels not
constricts them, so I doubt that Joy will offer the same advice.  But I
think that this creates a false sense of warmth at the skin sometimes
causing people to underdress, (and in football crowds partially undress)
to their possible detriment.

So, if you drink a bunch of spiked hot chocolate and think about going
to sleep in the Vanagon during the Alaskan winter with just a sheet over
you, remember that your body may be playing tricks on you.  Of course,
by then you may not care.
