Interesting, just saw this on Yahoo:
Internet addictions: A real medical menace? : Christopher Null : Yahoo! Tech
A psychiatrist is suggesting that internet addiction be added to the Manual of Mental Disorders, which must be the psych's "go to" book. I totally agree since we have read about parents completely ignoring their children while addicted to games...to the point of death in that one recent story.
Ah hem, this line certainly describes me:
constantly on the computer as a way of connecting to the outside world.
yep, I am trapped in this window-less lab and in between testing patient samples, I am on the internet!!!!!

Good thing I still know how to log off and tend to my real life. Sometimes.
