Looks like you have too much time on your hands. I too was way too much on the internet. Then I started my masters in college and BOOM, many hours, almost whole days pass by without me checking facebook every 5 minutes. But I do admit, sometimes I think about facebook before falling asleep at night
The bottom line: the more occupied you are, the less pc time you have...
I also like to think of it this way: its more cool to actually have life, and be living it (going out and doing things, even just watch episodes on my pc
) instead of statusing about it on facebook
