First of all, I am not an expert. So I might be thinking wrong.

But it sounds so wrong. Some people gets it even when use it just for one time. I mean it doesn't work like drugs. There's something more complex behind of this thing. It is probably change the settings of the brain. Whatever it is, it is also keeps away from healing itself. I mean for example, when you have chemical imbalance or neural stuff, it is usually getting fixed by time. If it is a chemical, body neutralizes it. If it is a chemical inbalance, body fixes it. But whatever this is, it doesn't gets better.

So we have these questions in general.

Do PSSD impacts the correction system of the brain?

If it does, Does the same apply to other parts of the brain?

When you have windows, you're basically getting closer to the intact version of brain. So why it turns back to PSSD again? I mean why improvements are not permanent? Is it because of PSSD getting worse over time. If it does, why there are people getting better over time? We need to answer these.

If we use logic, we can find the reason behind it. Because when we try to find with practice, it is getting more confusing and we can't even find something. Some dude takes antibiotics and he is getting cured. Some dude takes some kind of vitamin and he is cured. But we know the mechanism basically works same. That's why we all have the similar and same symptoms. Emotional numbness, sexual disorder etc. So I believe that we shouldn't trust practice unless it gives the same results for the majority.

So let's think about it. If we know the mechanism of the brain and how ssri works, we can find something.

For example, not every antidepressant gives the same results. We can find the difference and we can learn what causes to difference.
