I made it over a month of semen retention aka no busting nuts because of no internet and cable TV at home.
Did you not have a lot of withdrawal symptoms as you left not only porn which is crazy amounts of Dopamine but also Internet as a whole which also releases some Dopamine? I realized for me giving up both at the same time is too much. Lately I have restricted my internet and put a block from 8 pm till morning and it's going ok.
