I took CBD twice and both times it worsened my sleep, so I really wanted a pure CBN product.

Not sure where you live, but this is what I use for CBN: https://www.charlottesweb.com/products/stay-asleep-cbn-gummi...

One gummy (10mg) works for about 2-3 nights, then I get another 2-3 nights effect with 20mg. Then I have to cease taking it for several days.

Alas, they won't ship that product to where I live.
