If you serve alcoholic punch, use a non-carbonated base, such as fruit juice. The body absorbs alcohol faster when mixed with carbonation. Do not force drinks on your guests or rush to refill their glasses when empty. Some guests may not wish to appear rude and will accept drinks they do not want. Stop serving alcohol about two hours before the party is over.
Guests then have time for their bodies to absorb the alcohol consumed.
Serve coffee or other non-alcoholic beverages as well as food. Offer high protein food like pizza, shrimp or spareribs. Offer to make the next drink, using less alcohol and mixing it with a non-carbonated base. If one of your guests has been drinking and shouldn't drive, please don't give them back their car keys and let them drive. They could hurt themselves or others and maybe just a little persuasion from you could mean the difference between life and death.
