Experience with CBD oil?

Has anyone tried CBD? What has been your experience? Have you used it while breastfeeding? Did it have any effects in your baby?

My back hurts a lot from scoliosis. I've been looking into taking CBD to take the edge off before bedtime. I exclusively breastfeed my 3 month old baby and would probably use it after she goes to bed. She's been sleeping from 11- 7am consistently. I don't like the grogginess from weed.
