YOU Tip: Night-Night No-Nos

Generally, we don't like telling you not to do something -- unless it's smoking, slurping trans fats, or spending 16 hours in front of the tube. But for optimal sleep preparation, there are a few things you should avoid to increase your chance of falling -- and staying -- asleep.

One and a half hours before bed:

• No alcohol or nicotine.
• No exercise that makes you sweat (unless you're already in bed, nudge nudge, wink wink).

Three hours before bed:

• No caffeine -- that includes caffeinated beverages, food, and pills.
• No eating. This will help avoid reflux issues that can disturb sleep.
