When you learn that CBD could be something to help you sleep, it may seem counterintuitive to try the cannabinoid for any other reason. However, CBD doesn't seem to make everyone sleepy. In fact, it may help with not feeling groggy. In 2014, a review published by Current Neuropharmacology examined the possible efficacy of CBD to help people with insomnia be more wakeful. The research indicated that CBD may actually promote alertness during awake times even though the mechanisms for why were not clear. Of course, more formal research needs to be conducted.
