Severe Insomnia with Fibromyalgia - How to Cope

Does anyone suffer from insomnia with their fibromyalgia and, if so, what helps you? I usually fall asleep easily after taking 75-100mg Trazodone, 2.5mg Melatonin, and sometimes one hemp gummy. But I wake after about 4 hrs and can not fall back asleep. I feel like my nerves have become awakened, which wakens my mind, preventing sleep. I've tried taking another Trazodone or gummy in the middle of the night, but neither helps me fall back asleep. I have pain and all the other fibro symptoms too but feel I could better cope with those if I could get a decent night's sleep. I don't take any of the meds meant for fibro. For supplements, I take magnesium glycinate, fish oil, B1, D2 and calcium. My dr suggested CoQ10 but that seemed to make my insomnia worse. She also suggested high potency B vitamin complex, but I think that might also negatively affect my sleep. Any suggestions would be welcome.
