Yes, days without is very artificial I think.
Also to be honest with yourself is really important. So, I would like to praise your courage and honesty in saying you "changed to light stuff" because that's really important you have good self-awareness and you are showing that by making such a statement. I feel you are still not comfortable with that part of your behaviour - but it's not coming out via porn but another way. So, deep down, maybe you still feel uncomfortable that the root of the problem is still there. It's not so much the porn (which is very bad) but the fact you are transgressing your own boundaries that you have made for yourself. This is what I found personally. Are you really happy with YouTube? Probably not. We all want complete release from this, not merely a step-down.
Positive things instead, like you suggest, meditation and so on that help sooth and calm down the things we otherwise try to use porn for. So, recognizing first how and why you want to use porn is a key step to then figuring out what other (self-positive) things could replace that for you.
When I got angry with women, I realised that this was also me rationalising my acting out. I would say to myself, "that woman treated me badly, so I am going to treat all woman badly back through using porn" - may not really clearly and consciously like that when I was in my bubble. But now I look back, I can see a lot of that in my actions. "Women don't like me, so I don't like women and acting out through porn is me getting my own back" - that's really warped and shows how badly my self image has got damaged over the years. I am trying to accept this about myself. It's not easy because no-one wants to think things like that. And yes, I was very angry too but totally detached from it and avoiding it. I had no positive outlet for my anger. (I think maybe of doing martial arts or boxing now instead, as much more positive).
People only have the power over your life that you give them. The anger is all yours.
