I spend hours per day browsing internet. It seems like I am addicted to it. However when I travel overseas or do some hiking, I find absolutely zero withdrawal symptoms, even if I am offline for weeks at a time. The real addiction I have is not to the internet, but to brain stimulus. I hate boredom, and when I'm static, boredom sets in and makes me want to get online to get mentally stimulated. When I do some work around the house, talk to someone or travel, my brain is stimulated enough to not have a need for internet.
