The daily grind can zap your ZZZs. Overwork may soak up the hours you need to spend in bed. Or family commitments or stress may keep you from falling asleep or staying asleep. That can leave you tired, groggy, grumpy, and even sick. Getaways are great for naps and snoozes. And if you plan your trip in advance, you'll sleep better both before and after your vacation.
