I just don't know what to do. Every night around 3am DH starts moving and thumping around in his sleep. He's a big and heavy man and when he starts flopping his arms and legs on top of me it wakes me up. I'm a really light sleeper, he is the total opposite and once I'm awake I just can't get back to sleep with him acting like a nocturnal octopus next to me. He doesn't realise what he's doing but it doesn't affect him, only me. I end up starting my day at 4am after about 5 hours sleep max and I'm SO resentful but feel unfair blaming him even though it's his fault. He works shifts and I literally can't wait for the one or two days a week when he is on a night shift. We don't have any spare rooms so neither of us can move elsewhere. I just don't know what to do about it but something needs to happen because I'm in a murderous rage every night desperate to try and get to sleep whilst he is happily windmilling next to me. I have mentioned it to him of course but how can you stop doing something you don't know you're doing in the first place? I feel so resentful that he gets a great sleep every night but because of him I'm exhausted every day.
