A new study, carried out by researchers from Rhode Island and Massachusetts, has revealed that "sleeping it off" after a night of heavy drinking is not enough and will not dim chances of the drinker being sluggish the next morning.

The study, released today, has asserted that the effects of alcohol manage to last much longer than earlier estimated, and even after the alcohol is out of the blood, which not only leaves the drinker with a bad hangover, but also affects the brain's functioning, thereby slowing reaction times and the ability to concentrate.

The researchers have discovered that it does not matter if the liquor consumed was clear or dark, the affects will stay.

"People will be impaired the morning after - after the alcohol leaves the system", Dr. Damaris Rohsenow of the Brown University Center for Alcohol and Addiction Studies in Providence said.

For the sake of study, effects of heavy drinking were studied for 2 straight nights on 95 youngsters from the age groups of 21 to 33, and conclusion were drawn on the observations made.

The findings are all set to be published in the March issue of Alcoholism: Clinical and Experimental Research.
