I did this in 2008 when on a trip in my home country where network coverage was so bad and power sockets so rare that a smartphone was basically useless and more likely stolen from you if you show people you have one.

After that that, my cyber-addiction has mostly stopped: I can go without a computer big or small for months (but then I would need the good old paper for various needs) and not give a damn about likes or karma or even toxic comments.
