Try to steer clear of all substances before bed. If you generally struggle to sleep, this is especially important. For sensitive people, caffeine is best avoided for many hours before you want to go to bed, and for some it’s best avoided altogether.It’s also best to avoid alcohol. Even though drinking can make it easier to fall asleep, it makes staying asleep harder and it wrecks the quality of sleep—as most of us well know! What’s more, relying on alcohol to fall asleep just replaces one drug with another, which probably isn’t what you’re aiming for when you stop smoking weed.
