Different relapses?

It depends on a lot of factors.

How long are your streaks ?
How many times do you relapse ?
What is the type of relapse - repeated fapping for days on end or a one time fap ?
There are too many unknown variables about your journey to give you a considered answer.

One thing stays true however, dopamine is the wanting/craving/memory chemical which is released in huge amounts by fapping to porn.
It will destroy some of your dopamine receptors if you continue to fap to porn - 100% certainty, and you will go further down the rabbit hole of despair if you do not take nofap seriously.

Slip ups or relapses are part of the nofap journey, but you should not normalise them by claiming that some help you.
This is not a criticism, but a comment from a past addict who knows every trick the brain uses to keep us fapping to porn.

Cheers for now.

 

It sounds like you are stuck in a loop of your brain telling you it wants dopamine, and then you finally give in, and you get stress relief from the PMO because it basically knocks out your brains ability to feel normal stimuli.
I am not a doctor or mental health professional so my answer is just some guy off the street's opinion, but it sounds like you are having a stress induced relapse.

Keep in mind, that PMO increases your stress threshold, and that is funny in a way because most of the time we fap to porn to reduce stress.
But in time PMO actually causes more stress, and in your nofap journey this stress builds up until in a moment of weakness you relapse.
This gives you a short term stress release, but it soon begins to build up again and you go around the PMO roller coaster one more time.

Basically, you are stuck in between mood changes caused by your nofap recovery and your brain making you feel bad to try to get you to flood it with dopamine by porn again.

If you do not decide to completely shoot for recovery, and you need to budget in at least 90 days nofap for that, you will continue to ride the mood swing roller coaster for the rest of your life.

So you have a decision to make, 90 days NoFap, with no extended multi-session relapses, or mood swings all the time.

Again, that is only my opinion, see a proper mental health therapist for a professional opinion.

Good luck and cheers for now.
