This was what I found out and concluded over the past few months being in NoFap. It's a harsh reality that I took a while to be at peace with. It may not even be 3 or 4 days. I concluded that it may even be 1 or 2 weeks for some people. The problem here isn't the days, it's the amount commitment and improvement you want to put in. That's the real problem. I've seen so many people here saying that they are stuck in their reboot, where they will relapse constantly in a 3 or 4 days cycle. I'm sorry to say this, but let's face the harsh reality. That's not rebooting. That is basically a porn addiction but just that the duration between each relapse is longer than your previous "more addicted" self. Notice how I used the inverted commas? That's because there is no such thing as being more or less addicted to something. If you're addicted, it means you're addicted. Relapsing in a 3 days cycle is just as bad as relapsing 3 times a day. "Why? But at least I'm not relapsing as often as before. That's improvement right? " Some of you may ask this. But no, that's no improvement. The only improvement I can see there is that you're able to tolerate the urges just a bit longer. But is that really what you're aiming for? Changing from 3 times a day to 1 time in 3 days? It may not seem like you're deliberately wanting to relapse in 3 days. In fact, you will be thinking that you're trying your best to keep the urges out. That's where the real problem comes in. Your commitment and improvement are not enough. You're not motivated enough to make the harder decision and say no to porn, and for that, you will never improve. You will never get out of this addiction. This was something I experienced myself. I felt so hollow, so depressed. I felt as if I can never improve. Then one day I finally came to my senses. I don't want to be stuck there forever. In fact, I want to have a better life, get better grades, get a girlfriend and just enjoy life! That pure motivation finally got me out of the 3-4 days loop. As of now, I'm in the middle of my 91days (13 weeks ) goal. I want you people to face the harsh reality that I did. You already did it once. You notice your porn addiction was a problem and came to NoFap for help. Let's face it again. Let's actually get out of this addiction. WE CAN DO IT!
