Strong coffee, black, with ice, just like my father used to drink, in the morning.
Only thing, I'm so used to strong coffee, if I have a weak brew (like at a convenience store) I end up getting a headache.
Get enough of them as it is but weak and/or no coffee will give me a headache like clockwork.
So, let that be the warnng, but who cares, there's nothing like a double shot of expresso, then a cup to sip!
I have to be careful of dehydration, though, because supposedly caffeine is somewhat diuretic (water sharing).
Maybe someone could verify that.
