Dad got out of the hospital last week. He's now on fentenol patch, and naproxen. We stopped naboline as it was making him really out of it. For past month he has struggled to sleep. He has so much brain chatter when he tries to sleep its scary. Scared to not wake up, mumbles, talking to people, laughing, all while asleep. Then wakes 20mins later and says I can't sleep. We have tried sleeping pills, melatonin and Ativan. Nothing is helping. He will get 5th round of chemo next week. Any suggestions.
