Achievement Whore

Where have I been the past few days I hear you ask - well I have been going to bed at 4am each day....because I've become an Xbox addict.
I've played console games for many, many years and suddenly - with the introduction of a new dashboard (that's the 'home' menu screen for any plebs out there) one that tells me what my achievement ratio is like, (achievements are won by playing games and doing difficult tasks in game) has made me quite...obsessed about the whole thing.
The first time D worked out the ratio from the information on screen we laughed and I gloated at how my ratio was higher than his.
The following day after unlocking new achievements I asked him to recalculate....and then several times a day since then.
Poor D.
I began playing games to get 100% complete or 1000 of 1000 gamerscore. I've done this with FIVE games in the last month - count them - FIVE!!!! And have now become a complete addict. Every night I'm just trying to get "one more score" as D heads to bed at 9am. Come 4am I'm blinking at the screen wondering where my life just went...

I've even joined A FORUM, yes a FORUM. to talk with other addicts (everyone seems awake at 2am) and get tips on achievements I'm struggling with (trust me here some are VERY difficult to obtain)

I've even started buying my old games from 5 years ago on ebay so i can replay them - for more achievements. This is kind-of good as these games are mere pence now, but D keeps giving me the 'eye' particularly when he returns home and my "news of the day" is that I played monkey island three times today to unlock all the achievements and speed play achievements.

Heck as I'm writing this even I start wondering if I have a problem - but at the moment it's keeping me amused. By the end of December I want to get, and maintain, a minimum of 75% completion achievement score across all the games.
And obviously get as many games as I can fully completed
