it sounds funny but i have similar issue, just in a different way.

luckily my job is music. predominantly djing. i am so damn lucky.

but when it comes to production, it's a real nightmare to get in that studio. once you've had a full weekend djing, music music music, it's like.. 'right, i need to sort my regualr life shit out'. everything else takes over. bills, sorting djing stuff out, whatever... it's really difficult to find the time to actually get in and do what you love the most - MAKING MUSIC IN THE STUDIO!!

the way i see it is you need a schedule. a timetable. and you need to stick to it. it's called time management and it sounds boring and acedemic, and it is, BUT it gets you in the studio, it'll give you time for the missus and it'll make you feel much more in control of what you do. and happier.

plan your week and stick to it. i'm shit at it but i do have a regualr plan that i try (but never really) keep to. otherwise you just dont get shit done.

buy some books on the subject if you can mate. time management. it'll be well worth it i promise.
