My mom would drink on a pot of coffee for an entire day and night. Just heating up a cup at time in the microwave.
In the early 90s
The guy i worked with when i installed hardwood,tile, laminate and carpet
Had a beer stein with a silver flap lid on it
It held a whole pot of coffee
This was before the oversized containers that we have now.
He'd drink 5-6 pots of gomart coffee before 11am only gomart not that nasty 7-11 coffee
Then he'd drink 2-3 3 litres were available back then of Pepsi or mountain dew the rest of the day.
Often he would go to the pizza hut bar and fold 3 large pizza's in half and eat them
They were not happy about that.
We went to Golden corral and he took the stainless steel tub probably 5lbs of bourbon chicken that one slowed him down a couple day's
Severe diarrhea.
Lost his legs a few Year's ago diabetes says he feels better than ever plays golf weekly if possible.
