Coffee and caffeine......
Good for you/Bad for you.
You don't have to look far to find statistics backing up whichever position you take on this issue.
Like many, our home coffee maker has a timer. Our first gentle nudge toward wakefulness is the initial gurgle of near-boiling water being spritzed over fresh ground coffee downstairs in the kitchen.
My Old Man drank tons of it. He'd brew a pot in the morning, drink two cups before leaving for work, then put the rest of the pot in a quart thermos. The thermos would be empty by Noon, so he'd order a cup or two with lunch at one of his favorite restaurants, then ask them to refill the thermos as he paid for his meal. That quart would be gone by the time he got home, so he'd brew yet another pot to share with Mom during and after supper. I don't know how he did it..........he still slept like a baby.
I once attended an Army school where they had a "coffee club".
For $10 a week you could drink all the coffee you wanted during breaks between classes.
I found that 8 cups in 8 hours made my hands shake like a palsy victim and kept me tossing and turning most of the night.
I guess I'm not my Father's son.
I like my coffee strong and black. I've found I can drink two cups in the morning before going to bed with little adverse effect.
I drink a cup when I wake in the afternoon, then grab another as I go out the door to work. I'll normally drink another cup or two sometime during the evening if it's available in whatever E.R. we get dispatched to.
Six cups, spread out over an 18 hour period, seems to be my comfort level.
I've found that if I skip my morning cuppa prior to hitting the sack,
I wake with a slight headache that will only go away about two or so hours after I've had a cup of Juan Valdez's magic potion.
One more thing..........
I like Arabica, and I brew it myself.
I'm too doggone cheap to pay $4.00 or more per cup to satisfy my drug habit!
