I found that I will check my email, facebook, etc, is my laptop is by be. I don't know why, I just subconsciously do it. That means I am probably addicted. haha
To remedy that problem, I take the battery out of my laptop.
If I really need to use the laptop, then I have to go through the effort of grabbing the battery and putting it in. If I really wasn't going to do something productive with it, then the extra time makes me reconsider my actions.
