A member asked:

Is 2 cups of large starbucks coffee a decent amount of caffeine and will it last throughout the day raising heart rate,,,,,also take luvox?

Depends: People metabolize caffeine at various speeds. Thus how long the effect of caffeine lasts depends on your genes. It can certainly elevate your heart rate when the dose is high enough for you. There is a genetic test for this if you are really curious.
