Can drinking alcohol cause sleep problems?

ANSWER

While alcohol may sometimes lead you to fall asleep, the quality of sleep is often fragmented during the second half of the sleep period. Alcohol increases the number of times you awaken in the later half of the night, when the alcohol's relaxing effect wears off. It prevents you from getting the deep sleep and REM sleep you need, because alcohol keeps you in the lighter stages of sleep.
