I've quit drinking by taking it one day at a time. I haven't had a drink in six years now. I've also quit internet porn the same way. It can be done. I will be praying for you but I would also urge you to look into different addiction recovery programs for ideas and maybe even support. A.A. is a program that can fit pretty much any kind of addiction, even porn addiction. You have our support in here as well. There have been others who have done what you are proposing, and have had some sucsess with it. It's a good idea, so go ahead and give it a try.

God Bless you, brother!
With Love in Christ,
Chris
