Cbd for fibromyalgia

Hi
I have been struggling with my fibromyalgia since having radiation for breast cancer last April, after 2 surgeries. My Dr decided I needed a colonoscopy in Dec. I can't seem to bounce back. Having horrible fatigue and depression, also anemic since radiation. Wondering if others have tried cbd For their fibromyalgia symptoms and sleep. My go to in the past with fibro was cyclobenzaprine 5mg. I was on 5htp for the last 2 yrs and it helped but since the radiation and being taken off hrt it doesn't seem to be helping.
