Some people can be overly sensitive to CBN and only need a small amount to reap the benefits. Even taking too much for someone that’s not sensitive can result in a kind of hangover. My suggestion is to stick with it and allow your body to adjust. I know in the moment it sucks but that’s why you’re trying it to begin with, you can’t sleep. You may need 5-7 days to get used to it or find the dose that fits your needs. Like any other new medication the name of the game is low and slow.
