I know this will sound totally stupid to a lot of people, but I really struggle to organise myself into bed at a regular time, and I am chronically underslept pretty much all the time. I work shifts and am out of the house for 11-12 hours a day, getting home at 6.30 - 21.45, depending on the week. I can't catch up via lie-ins since having DS (now 11). I know what I need to do, but find it so hard to prioritise sleep 
I spend less time asleep than I do at work, and it's slowly killing me. Has anyone else been like this for years, and eventually cracked it? TIA.
