Let me think.

I arrived in September of 2009. Or 1998, depending on your worldview. It is now September 2011. I've been home three times, for a grand total of one year, which would place me close to the three-year mark since my arrival on the good ship misery.

Now, when did I become accustomed to dealing with the utter rubbish forced upon me by this cesspool...

Three years. If one considers 'jaded' to be a synonym for 'accustomed'.
