Great article, it makes me wonder about myself having an internet addiction though (which wasn't the main point in here, but still).
Most of the times when I try to escape from stressful things in my life, I go and watch videos, I can do that for hours, to the point where I don't have a good sleep, but on the other hand, I can go and be off that habit for weeks or even months, because I can actually handle it, and socialize with friends, and I've never had withdrawal effects from cutting down on my obsessive internet usage, it is weird ._.
