As unfair as it is, even brides and grooms can be struck down by sickness on or right before their nuptials. It might be something minor, like a cold or allergic reaction, that responds immediately to antibiotics. Too often, however, illnesses that must run their course (here's looking at you, stomach bugs) are the culprits.
If you suspect that something's amiss in the days before your wedding, by all means hit the doctor's office to catch it as early as possible. No one wants to spend her wedding or honeymoon feeling feverish and miserable! If you're unfortunate enough to get sick on your wedding day, medicate as well as possible and be sure to consume plenty of fluids. You're supposed to leave your reception in a limo, not an ambulance.
