Ron - Not to be graphic, which means I'm about to be graphic -
But don't you find having coffee without any solid food on an empty stomach kind of makes your poop all splashy?
(That was a way of avoiding saying diarrhea, but I guess no reason not to just say it.)
Actually, my wake-up time has normally been 9:30 to 10:30 a.m. I suppose you could say I eat a late breakfast at the lunch hour. I have coffee but don't want to spoil lunch which is usually an hour or two away.
Lately, however....the past week actually...I have been waking up by 6:30 a.m. I don't know why. So, I have been eating a couple of slices of toast or a bagel.
It works well enough.
As for that delicate "condition" to which you alluded -- the Hershey squirts, as it were -- I haven't experienced it as an after-effect of no breakfast. Not yet.
Hopefully never.
