The habit: A Diet Soda Addiction If you can't get through the day without a diet soda fix, you may be hooked on the caffeine."There is about as much caffeine in one can of [diet soda] as there is in a shot of espresso," says David J. Having a few cans a day could leave you feeling high, and then low when you come down from the caffeine buzz." Besides triggering major dips in energy, reaching for cans as a pick-me-up makes it tougher to fall asleep in the normal 30-minute range come bedtime.

to keep the caffeine from interfering with your sleep patterns.

Try rinsing your mouth with water after drinking soda to reduce the effects of its enamel-eroding acidity. The habit: Popping Sleeping Pills "Many people take over-the-counter sleep aids that are a combination of painkillers and antihistamines, such as Tylenol PM or Advil PM," says Dr. "If you're a healthy person who wants occasional help falling asleep, there's no need for the painkillers." Acetaminophens such as Tylenol can damage liver if taken long-term, and is even more damaging if you've had alcohol, since the liver has to work over-time to metabolize all those toxins.

A common cause of ulcers is regularly popping ibruprofen, such as Advil, because it affects your stomach lining.

Lessen the impact: If you you're going to take something to help you sleep, try Benadryl instead of an OTC painkiller and sleep aid combination.

"The safest amount of alcohol to imbibe is about two drinks a day for men," says Dr. "Binge drinking raises blood pressure, which offsets any of the cardiovascular benefits of moderate drinking." Moreover, heavy drinking zaps your thiamine (B1) reserves, which is needed for a healthy nervous system, and raises your risk of breast cancer.

Lessen the impact: Enjoy a glass of wine with dinner (pinot noir is high in resveratrol, an antioxidant linked with heart health and anti-aging) or a beer, but just don't have the entire bottle or six-pack.

If you're at happy hour or a party, try adding seltzer water to your wine.

The antihistamine ingredients minus the painkillers will help you snooze with less risk of liver damage or stomach irritation.

Just be sure to take a dose one to three hours before you plan on hitting the sack, because it takes longer to take effect than say, Tylenol PM.3.
