How long does a cup of coffee makes up woken ? Give me specific answer and be marked brainliest....
Surya316:
according to studies, coffee can slow down our nervous system which can cause problems. better you sleep for just 6 hours and study for the rest of the time. drinking coffee won't help at all as in the starting it would help you not to sleep but having it for long time won't do the same thing.
