A new study shows that us coffee chuggers don't get a supercharge from our coffee - rather it just brings us up to normal awake levels. Apparently we're extra tired in the morning from the hangover like effects of caffeine addiction.
Bristol University researchers found that drinkers develop a tolerance to both the anxiety-producing and the stimulating effects of caffeine, meaning that it only brings them back to baseline levels of alertness, not above them.
"Although frequent consumers feel alerted by caffeine, especially by their morning tea, coffee, or other caffeine-containing drink, evidence suggests that this is actually merely the reversal of the fatiguing effects of acute caffeine withdrawal," wrote the scientists, led by Peter Rogers of Bristol's department of experimental psychology.
I know how to fix this, - drink more coffee!
