I had medically diagnosed insomnia for a period. If your insomnia is anything like mine then you'd have a decent idea about if you're going to sleep that night or not. If it's 1am and I'm still wide awake then I'm not getting quality sleep that night. What do you have to lose by going to your PC at that time and working for 6 hours before work? You're going to be tired tomorrow anyway any attempting to sleep for another 5 hours isn't going to help.
