Hey Artemus.
You say that you went 120 days without porn. That's a Herculean effort in itself. The longest run I've had was 275 days without porn. But you know what's coming next, I slipped up once and started using again. The problem is that when we've racked up 120 days, we kind of forget the fire we had in our bellies during the first 20 days. When the cravings start for me I just scream 'NO' to myself inside my head. There's a voice inside my head constantly telling me 'go on, just 5 minutes won't hurt', but 5 minutes turns into an hour, which becomes an hour every day, which becomes wasting my life watching porn. I have to be honest, I don't know if I can do this, but when I see what was possible for 275 days it give me hope. At 120 days you just needed to go another 24 hours. That's not an impossible task is it. If I told you to go 24 hours without porn. It's difficult, but it's not impossible. At 121 days you just had to tell yourself to go another 24 hours, and so on.
I did something pretty drastic during my last reboot. There are a couple of problems I found with this 'solution', so think really carefully before attempting something like this. I bought a chastity device. At first it was uncomfortable, but after a couple of days it was barely noticeable. When I came home from work I locked myself up, went outside and put the key to the device in my car and went back to my apartment. This did two things. Firstly, it's there. You can't forget about it. It was a constant reminder that I mustn't watch porn. Secondly, masturbation was impossible. Even with the chastity device on, I sometimes found myself with porn on my computer screen. It doesn't stop you from watching porn, it doesn't eliminate the cravings, but in order to masturbate I had to pull my pants up from round my ankles, get my car keys, go outside (hopefully it was cold or raining), get the key to the chastity device, go back in, pull my pants down by my ankles, etc. All this gave me valuable thinking time; time to cool off. Anyway, this took care of masturbation, which is a big trigger for me. Obviously, I removed the device when I went to work or when I was out socialising. I only used it when I was home alone, with too much free time.
The problem I discovered with this was that I could feel I had something around my penis, which was 'erotic'. This is a big problem when you're trying to keep porn out of your thoughts. Sleeping in it wasn't so uncomfortable, but waking up with an erection was incredibly painful, but that kind of helped me to focus. It's not a long term solution and in fact when I decided I'd had enough control over my urge to masturbate I just put it in a draw and never wore it again. It's just too easy to reach down and start stroking myself when I get hard to some kind of erotic thought or image. Hence a relapse and why I'm back here again. I still have the device, but I haven't used it during this reboot yet. Hopefully, I won't have to. But of course, it doesn't deal with porn and the internet, it just means you don't get your 'prize' at the end of it. In hindsight, I'm not sure if this was a great idea by me, but it's a short term solution.
Have you tried hypnosis?
I'm coming up to the 30 days of this reboot. This one seems a little easier than the others. I think it's because I had several long runs of no porn, and even when I relapsed I wasn't watching porn every day, and more importantly for me, I told myself not to edge. Just watch some porn, get the job done, and get on with the rest of my day. Not great, but a big improvement on my past porn consumption habits, which involved hours and hours of edging. I think if we can get three or four long porn free runs, it weakens porn's grip on us. I feel that this is doable this time. I'm at home on the internet for hours on end due to the the Covid situation and it's been pretty easy to fight the porn urges so far.
It's shit! I know how shit it is when we keep going back to porn; sat at a computer with our pants round our ankles, penis in one hand. It's pathetic! People do quit though and so can we.
Take it one day at a time. Counting can be good, but it can also be a little depressing. Just wake up and ask yourself "what am I not going to do today?" If you get urges, stop them early and go and do something else. Go outside!
I really get a sense of pain in your post and it made me a little emotional. It breaks my heart to see someone suffering like this. it really does. I know how low we can get with this. So, I'm asking you, not for yourself, but for me, to beat this addiction. If I know you can do it then I know I can too.
