First off, RELAX. You didn't gain all of the weight overnight, and it's not going to come off that fast either. Patience is your friend. Now, are you drinking enough water? Eating enough? (Yes, I said enough.) Working out too much? Getting enough sleep? Did you have a salty meal? Is it that time of the month? There are a million things that affect your day-to-day weight. However, if you maintain a healthy diet and exercise plan, the weight will eventually come off and stay off. If I were you, I would take a deep breath, have a glass of water, a healthy snack, and kick my husband in the a**. He sounds like a jerk.
