Day 1.
I've been in a 12 step program for years that's helped my abstain from porn for various lengths of time. I've had numerous reboots, though I never used the word reboot until now. Abstinence from PMO produced major breakthroughs each time in all areas of my life.
For the last 5 years, I've gone no longer than 2 weeks of abstinence, and it wasn't intentional abstinence, typically low libido due to stress or anti-depressants. Typically I PMO once or twice a week for 15 minutes max.
I have a 10 month old baby with my girlfriend. I'll be 40 years old in a month. I've fallen into a bit of a depression the past few months, whether it's because of lack of sleep from my son waking me up throughout the night or some sort of pre-40 blues, I know that my PMOing is contributing to how I feel.
This is the first conscious reboot I've done in probably 6 years. Didn't have this forum to aid me back then, feeling hopeful that I have this vast resource for support I can turn to when I hit the wall and start obsessing about looking at porn.
