Wedding anxiety making you crazy? Regain your sanity with these healthy habits.

Order the cake, choose the flowers, sign the contracts, make the favors...if you're planning a wedding, you probably have a to-do list longer than the Great Wall of China. Add these tasks to your everyday responsibilities, and without the proper stress prevention you'll be on your way to a meltdown. Fortunately, there are ways to stay happy and healthy while planning your wedding. Here's how:

Put it in perspective. "Any unfamiliar experience is stressful,"Sometimes sitting down and talking to a third party helps to put it all in perspective." So choose someone you and your fiancé are comfortable with (whether it's a parent, friend or wedding planner) and tell them what's on your mind. Suddenly, it may not seem so overwhelming.

Enlist a friend. Don't worry about imposing on people-your bridesmaids probably have more free time on their hands than you. So do yourself a favor by asking a friend for help, and have your husband do the same, Rolfes says. Your maid of honor can stuff the invitations, the best man will make sure all of the groomsmen get fitted, and so on.

Get your Z's. "Too much or too little sleep can increase stress and fatigue." So instead of staying up half the night to search the Web for the perfect centerpiece, save it for tomorrow. And try to skip those long afternoon naps. If you get your eight hours of sleep at night and you're healthy, you shouldn't need long naps.

Cut the caffeine. According to NHS, when people are fatigued, they try to compensate by drinking too much coffee and soda—and too much caffeine can contribute to stress. "Instead of coffee and a bagel," start the day with a high protein snack, perhaps a protein shake. And rather than soda, drink water throughout the day."

Watch the munching. Often busy brides try to alleviate their stress by overdosing on sweets and carbohydrates, which can cause fatigue and weight gain. When you see yourself putting on pounds before the big day, your pre-wedding stress level is sure to shoot through the roof. So have plenty of sugar-free gum, fruit, vegetables, and other healthy snacks on hand to satisfy your oral fixation.

Get a move on. Everyone should have a regular exercise routine, especially during times of stress. There's nothing better than a morning jog or an afternoon yoga class to shake off that wedding task tension. But if you just don't have time for a full workout, go outside and take a short walk."

Fill your tank. Since you're so busy with the prenuptial planning, you may not have time to make sure you're eating well-balanced meals. Or, Your body can become depleted from eating too much sugar." She suggests taking a daily multiple vitamin, a high B-complex and an absorbable calcium/magnesium supplement to keep your energy high and your body healthy.

Loosen up. You've heard the phrase "Laughter is the best medicine." Well, let's face it: Something unexpected is bound to happen with all of the tasks to complete, people to deal with and details to work out. The simplest way to keep your cool, Rolfes says, is to have a sense of humor.

A final suggestion. During the wedding hustle and bustle, it's easy to forget about living a healthy lifestyle. And as you develop unhealthy habits, stress becomes more difficult to handle. So make an extra effort to stay on top of your diet, sleep and exercise routine.
