When you start getting nervous every time you see capital red letters on a sign, billboard, etc.

when you find it very hard to peel yourself away from the pc just to eat.

When you're on the forums creating/reading/posting in a "You know you play STO too much when" thread.

You walk into closed doors because it didnt slide open automatically.
wait for the pop up menu when entering a elevater.
look for very rare MKXII when looking at the stock exchange.
think its lagg when in slow traffic.
your w a s and d keys have holes worn into them..

You know you play STO too much when:

You define a profitable day not by how much the Markets (NYSE, NASDAQ, etc) moved and how much your portfolios gained ...

but

... by how much EC you made from the Exchange and whether or not the trading level of the Dilithium Exchange is worth jumping in.

when you tap yourself on your arm or chest and tell your "none exsting" crew to beam you to work or school

...you find it impossible to ignore more than 20 people at once.

When you start seeing crewmen walking around in your house hallways.

Your Significant Other, is standing next to you naked, and you don't notice...

Your Mother is yelling at you to throw the load of wash into the dryer...

You run to the bathroom between loading screens, or when the game crashes to desktop...

Your dog is chewing on yer leg, cause you haven't fed him/her in a while...

You carry a notebook full of printouts from STO Wiki and self-made charts to help you plan your limited game-time while on a lunch break at work ...

What?
