Sleep 18 - Drink - Don’t have an alcoholic drink in the couple of hours before going to sleep.

YouTube video, “Is alcohol actually bad for your sleep?”

“Alcohol is a central nervous system depressant that causes brain activity to slow down. Alcohol has sedative effects that can induce feelings of relaxation and sleepiness, but the consumption of alcohol — especially in excess — has been linked to poor sleep quality and duration. People with alcohol use disorders commonly experience insomnia symptoms. Studies have shown that alcohol use can exacerbate the symptoms of sleep apnea.”

”Since alcohol can reduce REM sleep and cause sleep disruptions, people who drink before bed often experience insomnia symptoms and feel excessively sleepy the following day. This can lead them into a vicious cycle that consists of self-medicating with alcohol in order to fall asleep, consuming caffeine and other stimulants during the day to stay awake, and then using alcohol as a sedative to offset the effects of these stimulants.”
