Though a glass of wine may help you fall asleep, excessive alcohol use can make you wake up in the night. One theory is that alcohol suppresses the REM (rapid eye movement) sleep state that’s critical to a good night’s sleep, says Spielman. “One of my insomnia patients became remarkably better when he reduced his alcohol intake from 20 to three drinks per week.” Drink moderately, if at all; avoid drinking within a few hours of bedtime.
