It varies person to person. This is what I found for U.
People differ greatly in their sensitivity to caffeine; some individuals can drink several cups of coffee, tea or soft drinks within an hour and notice no effects, whereas others may feel stimulating effects after one serving. Caffeine does not accumulate in the bloodstream or body and is normally excreted within several hours following consumption.
Hope this helps U.

i did a paper on how tea is better than coffee.
caffiene takes about 20-30 minutes to take affect.
i have some links about coffee if you'd liek to take a look:
