I also have a full time job, with hours ranging between 6am-9pm (varies week by week) my job also varies on the days i work, including weekends
I also have a wife and 8 month daughter, so poker drops down the list of priorities

but i try and load games between 8-11pm (8-10pm for 180s) so the latest i play is just past midnight. If im on the computer during the day, its to study and review hands
I've just started playing mttsngs as my main game recently, so i too am still trying to work out the kinks in my schedule. I found that with my prior commitments, games like HUSNGS and cash games seem to be the best thing for me, due to quick bursts you can play before being interupted by marriage/kid stuff

But i prefer mttsngs because a. i think im better at them and b. they are more entertaining for me.
Oh yeah, as i havent mentioned yet, i am an aussie, residing on the mornington peninsula in Victoria
