Hey Aboodos
Yeah i think focusing on studies and reading are great productive ways of staving off cravings and keeping the mind busy, not sure if it's going to rewire the brain from porn addiction though, sounds like really person interactions are the best thing for that.
Other good ways to keep you occupied are taking up a hobby like a sport or instrument, exercising, socialising, walks etc.
As for those high cravings, willpower and mental resilience will be the best defence, but that can take time, I recently found that a good way to curb a bout of cravings is to get out my phone and play a few rounds of a fast paced game, like high difficulty tetris or Fruit Ninja, that takes up all your concentration and can help you last out the surge of cravings until they subside,
hope that helps!
