You have to figure this out. That is such a difficult way to live, it has got to be affecting how you feel during the day, and now it is a set habit. It might be worth talking to your doctor.
There’s very few things I know about, but after 26 years of flying night freight, I do know about sleep. Taken instruction every year in sleep. I’ve had to sleep during the day in hotels, where everyone else is awake, talking, watching the tv, hotel maids banging on your door. I have a few things that I recommend you consider, if you haven’t tried these.
Comfortable earplugs. Always. Absolutely no light, including from a clock, little red light from a tv, cover it up. No caffeine later in the day, not too much alcohol or sugar. Try sleeping for a few days in a separate bedroom then your husband (just for awhile, I know you may not want to do that, but experiment). Don’t look on your phone or do anything electronic in bed. When you wake up and you feel that urge to get up and walk around, don’t. Lie there instead and try to clear your mind and wait to go back to sleep.
Melatonin is mostly helpful as far as the waking up. The right amount should allow you to wake up, but then go right back to sleep, and you should wake up rested. The problem is, everyone needs a different amount, and you don’t know how much you need unless you titrate yourself. Most people that take 1 mg will feel like it does nothing for them, but some people have crazy, wild dreams, so they shouldn’t take melatonin. You shouldn’t take melatonin mixed with anything else, just pure melatonin.
To titrate yourself, take just 1 mg for three days. Make sure you have at least eight hours to sleep. And then every three days, increase the amount. The goal is, if you wake up, you go right back to sleep, and you wake up rested. That’s the right amount for you. If the dreams get too intense, that’s too much.
But, I know people don’t always want to try melatonin, they’ve given up because they think it doesn’t work for them. Maybe it doesn’t, for some. My husband occasionally takes Ambien when recovering from a tough trip, and he sleeps like a rock.
