caffeine is caffeine, in 'soda', coffee, tea, chocolate.
Some have more, some less (about 95 mg of that drug in that lill restaurant cup w/the tea like look; 39 mg in that 21oz [a Mickie D's) cola). The "Zero" U drink has 0 mg of caffeine (or is that for the amount of sugar?)
"...a little espresso maker..."
over the 95mg in the 'tea cup' looking cup (8 oz) due to brewing style, finer grounds, etc
I have a 16 oz drip, ona slo day a 2nd 16 of decaf. If I gulped (fast) an expresso - I'd buzz & sweat (for 10 min?).
but dont know it's mg dose. A friend hasa Mickey D's w/2 'shots' probably 250 mg twice a day. A lady I know
drank a pot of coffee a day as she puttered around. When in the hosp for another issue after a day or so she
started failing. The doc was smart & asked her adult kid her intake (she werent home & in regular habits). He
prescribed an amount of nodoze or sumpin equivalent and she 'came back' shortly. Much of the world is on that
drug'n nicotine. Founders of this country (& others elsewhere of the era) buzzed on alcohol most the day (hard
cider here, wine elsewhere) and as I look back at the hard life and what they accomplished, I can understand it...
