If you decide to quit going to bars to drink, thinking that it's the bars that's making you an alcoholic, and you'll instead just drink at home alone, you're in denial. You are in denial if you think your addiction is with EO. It's not. It's an Internet addiction, and retreating to the comfort of your Blog will not cure you.
If you were serious about your addiction you would find no need for a grandiose announcement as to your leaving, especially one with a time schedule as to your return, as if your time table or your addiction is anyone's concern but yours.
When your Internet activities begin to affect your daily life, your friends, your work, even your eating habits, it's time to quit cold turkey, or get a handle on things and know how to incorporate it into your life. You have to learn when to walk away, how to moderate it, how to live with it. Been there, done that. No need for announcements, just do it.
