Are you still looking at the clock hours later after trying to go to bed?
Nutmeg is such a wonderful herb that is totally under utilized. It's not just for spicing things up because it's also great for slowing things down.
Nutmeg works best when it's fresh so simply grind a little bit ( ~ 1/4 teaspoon) and add it to a cup of warm coconut milk with a hint of honey.
If you're not really into drinking milk you can try taking one capsule nightly and increase your dose by one capsule until sleep is regulated.
