How many cups a day ?

Only if you drink it after 4pm. I don't.

caffeine has a 4-6 hour half life.. it will take a full 24 hours to get out of your system.. although at lower amounts it still will prevent you from going into a deep sleep

the reason is the effects it has on suppressing GABA
that is why people who are addicted to caffeine are all nervous and have anxiety all the time. so if you do consume caffeine you need to supplement with GABA

A lot of people like coffee and I see no problem with it as long as it's not affecting you or you have it too late. I dont drink it much except weekends and when I do it's one cup. But I do like caffeine before my workouts. Just not from coffee

Moderation is key
