Have you been hitting the snooze button on your insomnia? Or wishing you could? For many adults suffering sleep problems, the challenge is not necessarily falling asleep, but staying asleep – and getting back to sleep if they wake in the middle of the night.

A prescription sleep aid, taken before bedtime, may help you fall asleep. But many of these  medications shouldn’t be taken in the middle of the night, when you wake up and can’t fall back to sleep, because they can leave you feeling drowsy if you try to function with less than eight hours of rest. In fact, the FDA recently issued a drug-safety communication warning on prescription sleep-aids about the risks of next-morning impairment.

“All drugs taken for insomnia can impair driving and activities that require alertness the morning after use,” the warning states. “Patients who take insomnia drugs can experience impairment of mental alertness the morning after use, even if they feel fully awake.”
