I suspect it is possible for a person to become an internet "addict", strictly speaking it would be a non physical dependency which is different to physical addiction. For example there is no such thing as a cocaine addict, there are however people who are psychologically dependant on cocaine.

Diagnosed under the DSM5 rules with autism spectrum disorder, under DSM4 psychologist said would have been AS (299.80) but I suspect that I am somewhere between 299.80 and 299.00 (Autism) under DSM4.
