* Tell your doctor about your efforts, and get her approval before using quitting aids such as nicotine replacements (gum, patch, lozenge, spray) or medication, which are generally not recommended for pregnant women, except for very heavy smokers.
* Write down when you're most likely to smoke. Then avoid those triggers. Always have a cigarette after a meal? Go for a walk instead.
* Give yourself a daily reminder of why you're quitting. Post a list of reasons -- or a snapshot of your ultrasound -- on the refrigerator.
* Stock up on oral substitutes such as sugarless gum or toothpicks.
* Distract yourself from cravings. Get a massage, paint your nails, knit, or do anything else that keeps your mind and hands busy.
