@keenly, you might have to experiment with doses, brands, and delivery systems. I take Plus CBL Oil in the 10 MG dosage, and it's really helped me with IBS and sleep, but not much for pain. My doctor recommended this brand, and he takes it, too. Plus also has a 15 MG, but it's too strong for me:

My integrative pharmacy also carries Hemp Fusion, and it helps my biofeedback therapist with pain. I want to try it sometime. It has lower doses of CBD oil, but contains other ingredients that are supposed to make the oil more bioavailable. My therapist takes the regular 3.0 dose.
