Why drinking coffee makes me sleep?

Question

.. what i know its supposed to make anyone ake up or not to get tirerd.. ifeel really sleepy everytime i drink a cup of coffee..

Answer 1

caffeine affects people in different ways.  Perhaps it has the opposite effect on you.

Answer 2

This used to happen to me too!  A cup of coffee before bedtime -- and people thought I was nuts when I told they I go straight to sleep!

Caffeine is an antagonist for some adenosine receptors in the brain, meaning they stick there instead of allowing the natural adenosine-bearing molecules act upon it.  When you consume enough caffeine over a certain amount of time, you are essentially addicted: the number of functioning receptors goes down, and the stimulant effect of caffeine is dampened and eventually practically gone.

Nowadays, if I want a cup of coffee to wake me up, I load it with sugar.  The sugar perks me up now, rather than the caffeine.

Answer 3

Answer 4
