It looks like having a nightcap may not be the best way to get a great night's sleep.

A new study has found that alcohol interferes with the restorative functions of sleep.

Researchers gave healthy male university students alcoholic beverages before bed. Their findings: drinking leads to insomnia rather than good sleep.

That includes difficulty getting to sleep, early-morning awakening, lack of a sense of deep sleep and difficulty maintaining sleep.
