So porn is linked to brain shrinkage/ less grey matter, how long until it is back fully healed and normal again?
I would say a full reboot should correct the issue, this also varies depending on the level and years of addiction.
About 15 year addiction from aged 13, not good, been trying to give up for 5+ years, best streak is 2 weeks, feel like a part of my soul and libido is stolen every time, anyway, I’m guessing using the brain to learn new things like a new language might help there
Most anything other than PMO will benefit you, taking care of your physical and mental health is a good first step.
