I have severe back pain and have taken conceivable pain medication, but nothing seemed to work. I came across the Oil Science CBD products online after my first purchase I consulted Gillian about dosage before use. We agreed on starting with the minimal dosage and working up to see what works for me. I now take the CBD oil twice a day (morning and evening). This helps me manage my pain so that I can get through the day as well as have a good night sleep. Subscription takes away the stress of ordering the product monthly as this is now done automatically for me and delivered straight to my door. I highly recommend Oil Science for their products and excellent service.
