Does coffee make you hard to sleep?

That's called having a tolerance

 

A lot of people can't tolerate caffeine in their system after 5pm I they want to be able to sleep well at night. However coffee may not be the real issue here so much as conditioning your mind and body's sleep patterns to naturally start sleeping later and later at night. Mental stress, staring at your computer screen too long, diet-- there are a whole lot of factors that can contribute.

 

Generally the caffeine in coffee should keep you up. But everyone has different body chemistry so some might not even be effected or have too high a tolerance to even have it effect them anymore.

 

Coffee and tea are elixirs. I like to believe they have a good effect on your body. Yes - they are refreshing.
I love this quote from Jerome K. Jerome:

“It is very strange, this domination of our intellect by our digestive organs. We cannot work, we cannot think, unless our stomach wills so. It dictates to us our emotions, our passions. After eggs and bacon it says, "Work!" After beefsteak and porter, it says, "Sleep!" After a cup of tea (two spoonfuls for each cup, and don't let it stand for more than three minutes), it says to the brain, "Now rise, and show your strength. Be eloquent, and deep, and tender; see, with a clear eye, into Nature, and into life: spread your white wings of quivering thought, and soar, a god-like spirit, over the whirling world beneath you, up through long lanes of flaming stars to the gates of eternity!”

 

more than 5 cup of coffee will have a bad effect on your sleeping patterns.. try to limit your caffeine intake.. if you want to sleep properly
