If I included by smart phone, which I guess I should I spend hours per day online. I still get other stuff done like work and studying so I am not that concerned yet. I don't watch much tv so I guess its kind of taken that spot in my life. Whereby some people can watch tv for hours in the evening, I go online.
If I wasn't getting to sleep or working etc then I would need to address my internet use. I do find it helpful to connect with others who would understand some of the issues I am going through.
