I log on between 7-8 AM , I log off sometime around 1-2 AM...I take a 5-6 hour break some days in between..and I sleep between 2-7 am...pretty much every day, same schedule.
I read other websites and do others things ... I am almost afraid to make a guess how many hours I spend here a day/week, atleast 12 a day...some nights I just can't leave the computer, you start IMing ior get into a good thread , next thing you know it's 3am.
