Hey guys, I know the theory for us young guys suffering from PIED taking way longer is sexual conditioning during adolescence, but what if for some of us our reward circuit/dopamine signalling remained desentisized after quitting and no matter how much time passes won't return to normal. Since joining this site a year ago Ive come across multiple stories of guys 2, 3 , 4 and 6 years no PMO in my case who are still suffering from PIED/flatlinining. I came across this recovery story on YBOP a few months ago: http://yourbrainonporn.com/ed-recovery-kickstarted-meth-after-long-reboot This guys went 5 months no PMO and still had ED issues, he got depressed and used crystal meth on a single occasion and 3 days later his ED was cured. He links a study in his story of mice addicted to meth : http://bioengineersatwork.blogspot.co.uk/2008/04/used-meth-tired-of-it-just-reboot.html 'Basically they had rats addicted to meth (which acts on the D2 in the striatum just like porn addiction does!) and then after discontinuing their brains would never completely normalize in that region. But they learned that just giving them the drug one more time only at a later date reversed and normalized the function. Like it jumpstarted it back into function' I wonder if the same thing would work with a single time use of cocaine considering it acts on the same part of the brain as meth/porn. Meth is supposed to raise dopamine 1200 times above normal and cocaine 500 times above normal. What do you guys think?
