I work midnights 11 to 7. I drink 20 ounces of coffee a night which is about 2 and 1/2 cups.
It might be too much for me to sleep well in the morning, but its enough to keep me awake through the night.
When I was younger, I used to drink about 40 ounces a day.
When I was in my 30's I thought several times I was having a heart attack. I went to the hospital had an ekg
visited my doctor he finnally told me to cut down on the coffee and exercise more.
Coke or pepsi can be just as bad or just as good as coffee for a caffene buzz. I think there is more caffene in
Coke than in a regular cup of coffee.
