Finding a natural way to fall asleep is the safest way to bypass all of the possible side effects AND to get some rest.
The first thing to do is to see if there are things in your lifestyle that are contributing to your restless nights.
This means making sure that your bedroom is conducive to sleep, removing distractions, and making the room comfortable.
If possible, ditch the bedroom TV, or only use it when you’re ill.
Nighttime electronics use has been linked repeatedly to being unable to shut off the brain at night and fall asleep.
The only things that your bedroom should be used for are bed things… sleeping, reading (before sleeping), or sex (that’s up to you).
