Are you a newlywed suffering from honeymoon hangover? It’s when the vacation in the Bahamas is over, the dress is put away and couples realize there’s an important thing they now have to face: Marriage. Dr. Phil is shocked to find how little couples know about each other before they walk down the aisle. Jeremy and Tamarra have been married for only eight months, and they wonder if their marriage can be saved. Jeremy says Tamarra is so clingy that he’s had to give up everything he enjoys in order to spend time with her. Tamarra says being married means doing everything together, so why wouldn’t Jeremy want to spend every free minute with her? Dr. Phil gives them a newlywed quiz. How well do they really know each other? Then, Mandy says her husband of three years had a 180-degree turn after they got married and changed his mind about an important value they shared: faith in God. Now, Nic says he’s an atheist, and Mandy is worried about what this means for their marriage and their family. Plus, Dr. Phil answers important questions from engaged couples: Should partners open a joint checking account? Do you need to get along with your future spouse’s family? How much do you need to know about your partner’s past? If you’re about to tie the knot, grab a pen and paper and make sure you know these important facts about your mate!
