yeah, that´s a common issue that every rebooter goes throught. the idea is not to starve the brain from dopamine, the idea is to replace porn dopamine with positive sources of dopamine. so do something exciting instead. talk to the addicted part of yourself. say: "bro, i know you really want that porn, but that shit is super bad for us, so let´s do x,y,z instead, and it´s gonna be super awesome!! ". and that´s it, talk to yourself like a friend, like a big brother. give your brain good replacements. that way both parts of your brain: the logic part (neocortex), and the reptilian part (where the addiction is installed), can be happy . this makes all the different in the long term.
