Is binge drinking only cause for the smell of alcohol on you the next day?

Alcohol can remain in your system for up to a day after you stop drinking, depending on how much you drank and various physical issues. While it is there, a small amount will be excreted in urine, saliva and sweat. Even after all the alcohol is gone, some metabolites will continue to be excreted. All of these may contribute to the smell.

Showering and a change of clothes will minimize the problem. For a total resolution, cut down your drinking to a couple of drinks a night -- if you can. If you can't do that, you have more problems than body odor.
