I was addicted to it for 6-7 years and I'm at the stage now where the addiction is very manageable.

I rarely ever feel the need to masturbate and the sexual thoughts have dropped. Before I'd used to think about sex 90% of the day, now it's toned down to maybe 5%. ( I feel that this drop is due to me not watching porn/masturbating anymore)

Accept that you're addicted to it and understand that it is definitely possible to stop masturbating/watching porn.

My number one advice is to stop everything you're doing and just go outside for a walk or run ( for at least 2 hours) away from your house/computer and preferably where there are people. You do this whenever you feel any of those urges. From what I understand, it loses those urges because you're taking a walk outside (energy used up) and your mind starts wandering about other things while walking (instead of porn/masturbating) plus there's people around you so that's another thing mind concentrated on. By the time 2 hours are gone those urges are gone and I'd do my best to just stay away from anything that could trigger me. You have to condition yourself to do this so that instead of taking the PMO route that'll definitely make you relapse you take the "walking route" that will definitely not make you relapse. So now you can build a road that gives you a choice, a choice to relapse or not. At least that's the way I thought about it.

I was where you were around 1 and a half years ago. Now I'm porn/masturbation free for 500+ days. You have to take this VERY seriously and be very vigilant at what can trigger you. And the good news is, after around 8-9 months it becomes tremendously MUCH more easier. It just does. After that it just becomes auto pilot. But for now you must stay away from anything that can trigger you and be super vigilant.
