Thank you for your welcome and your answers.
Welcome to the forum, ETC 
I looks that you do not suffer from cognitive symptoms in POIS, like memory problems, or speech problems, or loss of problem solving abilities, and so on. That is a good point. I do not, me neither, have cognitive problems from POIS, but we are a rather rare subtype of POIS. Many, many members have brain fog, no concentration, slow thinking process, when in POIS. And many have failed their exams because of that, or have lost their job.
However, I have much, much emotional symptoms, when I do not take my pre-pack before O.It looks like you also have much emotional symptoms.
To answer you,
- Memory problem: My memory is difficult to access during the POIS interval due to the heaviness of my state of mind, I have to make a painful and extra effort. I feel like I skipped everything that happened before the symptoms, like a "flush", but it's not as serious as that for me.
- Elocution problem: Words hardly come out of my mouth, they weigh very heavy as if I was giving birth to every word. I make an extra effort during the few days of the syndrome. This problem is combined with another emotional one, I approach my interlocutor less easily and I feel very heavy in his presence, very slow, depressed and everything I say requires extra effort.
- Ability to solve problems and to concentrate : I'm not going to lie to you but I always force myself. I will describe what I feel in a metaphor: "I force myself to the point of feeling like I have a knife in my head". I feel like I'm stupider than usual, like I'm in the clouds, like I'm not myself.
If I manage to force myself, it may be that the symptoms are not as serious as that. But recently I found out that the headache I suffered from during the POIS interval is insurmountable. If I had never worried until now, it's because I didn't imagine that there was a whole name for this syndrome, I just thought it was a condition that was unique to me and I could barely link it with O, but now that I have proof that this little-known syndrome can actually be a lifelong disability, I have totally changed my view, especially after reading the testimonials on the forum.
