For years I consistently couldn’t sleep until 3-4 in the morning no matter what I did. I never took naps. Never had electronics in the bedroom. Tried sun light, melatonin, benzodiazepines, you name it I tried it. Had been that way since I was a kid. I figured the only thing that would work to get a reasonable sleep hour would be to move time zones. I think I figured France time zone worked out. But finally after being given a high dose of ambian during one hospitalization I could sleep. So for years I was on 20 mg ambian ( twice the recommended dose for men) then I tried to get off of it with my current pdoc. He took me down slowly but no luck. But then he tried gabapentin so now I’m on 10 mg ambian and 500 mg gabapentin and can sleep at midnight.
