Is there a way to counter the effects of caffeine?

After I drink a coffee sometimes that caffeine high stays longer than i want and i just want it to go away! Is there anything i can do?Instead of just waiting for it to wear off?
Answer:
No there is no way to get rid of it faster. It is a stimulant and is much like a drug.
