I can share some advice based on my experience. Useful especially if you try hard mode.
Have you been using SPIN Browser? Some people say that is the safest browser for people addicted to porn, because it blocks many dangerous sites.
If your urges are strong and you are at the beggining of your reboot, don’t try to use it.
Yes, this browser is great. It limits the number of temptations and factors after seeing which you will aweken your addiction.
Yes, it is a good protection against pictures, movies, games etc. containing nudity.
But there are ways to bypass it - e.x. using SPIN you can download other browsers (assuming you blocked access to app store on your phone).
I tried it. If it weren’t for different blockades on my phone, I would kill my streak.
For someone like me, hard-mode is an only option - but SPIN can ruin it. So it is better to cut out your access to the Internet on the phone. At least until you will be rebooted.
That’s all. Hope it helps someone. Fight with all your might, folks!
