        For me, 1 20 fl oz cup of coffee, for my gf, anywhere from half a pot to 2 pots a day, and she sleeps better than I do

          I am too lazy to find sources, but I heard 500 mg is the limit (depending on weight and so on of course). That is around 5 coffees, give or take.

          No. Some people get jittery when they have more than one or have a cup too late in the day. But 400 mg of caffeine is fine. That’s four cups of coffee. Six or more a day can result in a rise in risk for cardiovascular disease. This could be considered not great, but a lot of other factors to into cardiovascular disease. So “quite bad” is quite a stretch.
