DH terrible sleep - help!

[isitwinetimeyet16]

Hello,

I am desperately trying to help my DH get to the bottom of his terrible sleep.

He wakes early and never refreshed - he is exhausted all day and it's really getting him down.

He has a job where he stares at a computer screen all day but he is very good at taking breaks etc. He's given up drinking to try to help but it's not worked. Other things he's tried - Mirtazapine, exercise, mindfulness, blood tests, sleep apnoea tests, bruxism tests....

Does anyone have anything else I'm missing? I just want to help him, it's miserable.

My mother has terrible sleep, rarely gets a full night, wakes at least once, only sleeps for say 5 hours a night. She's suffered for years with it.
I sleep for about 5 hours a night, I may wake up once or twice, and I almost always hear the dawn chorus, which is lovely. I have enough sleep and I don't moan. So we both have about the same amount of sleep but we view it very differently.
Does you husband actually need more sleep, or does he need more rest? If he spent a week telling himself that his body knows how much sleep he needs and accept this, then life might be more manageable for him. It worked for me because I didn't want to spend my life with my perceived lack of sleep ruining it.

Is it definitely sleep rather than something else that could cause tiredness (iron, thyroid etc.)?

Thank you both so much for the replies. I definitely agree about the acceptance - I also wake early but it doesn't bother me so I never really think about it. But I think because his job is so full on he struggles when he's exhausted. He's had all the tests for thyroid function etc and everything in normal range.

Has he cut out caffeine? Also the timing and type of exercise can really help. E.g I find swimming completely exhausting (but he might find something else works for him!)

He has cut caffeine out! For ages. No caffeine, no alcohol, no blue light in bedroom. He’s literally doing everything right!

Slow release melatonin?
