Exercise Rehearsal Dinner Restraint

Hosting back-to-back blowouts is twice the headache: “You shouldn’t be planning the equivalent of two weddings,” says Pryor. “Keep the rehearsal dinner very simple and different from the actual event―just cocktails and hors d’oeuvres, or a barbecue.” (Better yet: Let the groom and his clan handle the whole event.) And as tempting as it may be to stay out late catching up with out-of-towners, set yourself a curfew and stick to it. “Nothing good happens after midnight, and you’ll pay for it the next day,” says Karena Bullock Bailey, a wedding and special events planner in NYC. “Grab a couple of bridesmaids and exit gracefully―you don’t have to say goodbye to everyone.”

Designate a Wedding-Day Contact

Give someone the authority to make last-minute decisions and insulate you from snafus. If the chandelier plummets into the wedding cake ten minutes before the reception, you’re the last person who should be hearing about it. “Pick someone who you trust completely and empower her to make decisions in your stead, whether it’s a problem with the caterer or rearranging seating for a guest who’s a no-show,” says Anna Post, author of Do I Have to Wear White?

Eat!

“Not eating on your wedding day is the worst thing you can do for your nerves,” says Bailey. Yes, it’s natural to be focused on how you’re going to look in your dress, but face it: At this point in the game, what you put in your mouth isn’t gonna make or break your silhouette. “As soon as you wake up, have a reasonable breakfast with protein and some carbs―because once you’re wound up and nauseous, it’s too late,” advises Bailey. Continue noshing throughout the day and into the reception; having a nourished, well-tuned body will help your psyche follow suit.
