Dopamine Explained Makes Me Want To Quit

I'm new to the site and need some help and support.... so here's a quick backstory.
I always had a thought in the back of my head that porn was probably not the most sexually healthy thing to do. The concern began with weak erections. I started looking into erections problems but as a healthy 30 year the material I read didn't apply to me. I thought that porn was possibly desensitizing me and that I should just need to cut back. But soon I came across the Reddit forum NoFap while searching for a way to improve sexual performance. I soon began reading about PIED and everything made sense when it came to the effect on the brain. In college I went through a time where I was addicted to opiates for four months. It crept up on me after an injury and my doctor did a great job of explaining the effects on the brain and why I was addicted. I was able to quit rather easily but I wasn't addicted for very long. Once the habit seeking behavior of a porn addiction and the dopamine hits you get from watching it and the feeling of never being satisfied was explain to me. It began to make clear to me that this was an addiction and whether or not I had erection problems I have to quit for long term mental and sexual health. The problem I face now is that I keep slipping back and restarting. The access is completely different..... its always right there.
