trying to get work done in your spare time when your spare time is between 11pm to 5am is probably not a good idea but hey, it seems to work for me!
I work through the evenings at my paying job which means i don't get home till 10:30pm and I'm REALLY not a morning person so working through the night and sleeping late seems to be the least practical but most affective solution! Only trouble is because I don't exactly have a timetable I keep overdoing it and only ending up with about 5 hours sleep.
I can only hope my remaining brain cells will survive long enough to finish the 3 remaining mock ups I still have to do....
