Booze before bedtime may lead to bad sleep - CBS News:
"The research showed that people were able to fall asleep faster and displayed increases in slow-wave sleep (SWS) -- or deep sleep -- during the first half of the night. SWS consists of stage 3 and 4 of NREM sleep, periods when the body repairs and regenerates tissues, builds bone and muscle and is believed to strengthen the immune system. This is typically known as the rest and restoration part of the sleep.
However, people who drank more alcohol tended to have their sleep interrupted during the second half of the night. What's more, the REM sleep portion of their cycle was disturbed during sleep, including delays in first onset of REM sleep. "
