21. DON'T booze it up with a new guy.
"Imagine you have two brains. One weighs risks and rewards, keeps you informed about morals and ethics, and warns you about unwise choices. The other seeks pleasure and feel-good experiences, creates erotic appetite, and drives you to satisfy that appetite," says Brian Alexander, coauthor of The Chemistry Between Us. "As anybody who's been on a diet and has faced down a plate of gooey chocolate chip cookies can tell you, it can be pretty tough to resist pleasure under normal circumstances, but when you drink alcohol, you are helping to cripple your rational, reasoning brain and giving your pleasure-seeking brain a huge megaphone. So, let's say you're out with a guy. He's cute, but you're feeling just so-so about him and you probably wouldn't want to go out with him again. But to make the date a little more fun, you start in on the martinis. Soon all you can see is the cute. A few hours later, you're looking at a very awkward morning."
22. DO learn to really listen to the man sitting across from you on a date.
"He is telling you all you need to know those first few times you get together. Really tune in when he drones on like a mama's boy or blabs incessantly about his ex. If he's unavailable--married, moody, or obsessed with his motorcycle--toodles to him. Really hear what he's sayin' right off the bat, ladies, and you'll save yourself a whole lot of heartache down the road." --Maryjane Fahey and Caryn Beth Rosenthal, authors of Dumped

23. DON'T treat dates like performance art.
Remember, you're not only trying to impress the guy; you should be seeing if he's a good fit for you. "I tend to forget that and treat dates like I'm on a stage in front of an audience of one," says Smitten blogger Gena Kaufman. "I plan my wardrobe for hours, perfect my makeup, and once at the bar, it's show time: jokes, stories, hair flips, etc. If a guy seems charmed by my act, I consider it a good date. But then flash forward to a third or fourth date, when I realize that while I was so busy being excited that he liked me, I forgot to actually notice whether I was interested in him."
24. DO flirt.
"Make eye contact and smile at anyone who catches your eye for three seconds," says DeAlto. "If he is interested, he will approach. In a relationship? Keep flirting! Continue to make him feel like the center of the universe. It will do wonders for your connection."
25. DON'T forget your manners.
We can't imagine this is something you'd ever do, but a little reminder never hurts: Say thank you.
"Good manners have become so old-fashioned that men now wait for the thank-you at the end of the date as a way to see if she's worth seeing again," says Brian from New York City. "I don't care if the woman looks like Kate Beckinsale and has a Ph.D.; if she can't be bothered to utter those two little words, I am never calling her again."

26. DO order what you really want.
"Don't be afraid to eat like a man. A guy would love to see a woman with a healthy appetite."
