This was my first symptom, which I perceived the night of my shrooms intoxication, beginning about 5 hours after ingestion. While everyone was coming down, something in me snapped while I was trying to get to sleep, I felt it, and the room started moving out of control. It was pretty dark, the lights were off but across the room there was a small led light. The movement was in a pattern kinda, almost like a wave going from left to right around my head, as well as up and down repeatably. The led light in affect was moving around in circles. I had known about HPPD before I did shrooms and that night I kinda knew it was instantly. I got little sleep that night. Through that next week I had it stay quite the same, individual words on a page would move in circles, basically anything stationary was unhinged and move in some way, when I stared at walls, they would move up and down. At the end of that week I had my first bad "episode" this is when my disequilibrium started. I was looking at a wall move up and down, and my head went with it. Suddenly I felt completely off, like I was sideways in existence, I was looking at a wall but it felt like I was looking down, my perception in space was totally gone. This extreme feeling gradually fell to a baseline of a stormy ocean feeling, my visual hallucinations were represented by a feeling of them, the world moved and I felt it. Even when my eyes were closed, I felt it. This continued for like 3.5 months, when the internal feeling faded into to almost nothing. That extreme feeling happened a few times after the first time, but never to the proportion it was initially. The perception of movement while I was stationary took about another month to die down to minimal levels, by this time, the other symptoms of HPPD had been realized.
I think HPPD must be what I am suffering from, although I never got it diagnosed, I was unsure of this when it was just movement and dizziness, but now since the other symptoms, it must be. Most people with HPPD, symptoms gradually worsen to a baseline over the first couple of months, there is a considerable latency sometimes between intoxication and HPPD. I don't think it is that abnormal that my symptoms happened gradually, it is always uncertain though. In addition, my symptoms began shrooms night. I have no time where I can point to any head trauma, and I did not injest any substance that would be considered toxic, the hardest drug I did was weed and that only sparingly. Those times were stupidity on my part. I can almost correlate the progression of my other symptoms to those times I smoked.
"Is there anything you (or anyone else) have tried that you think is helping?"
I was prescribed antivert for dizzines and it worked on my disequallibrium when I was convinced it was vestibular disorder. I don't know if it was a placebo effect though. I had a couple bad episodes as well while on it. The funniest thing though that has help is watching TV, or playing video games. Things will not move while I do this, and my dizziness would disappear.
I don't know, the last few days I saw a relapse in some of my dizziness and movement, the side of the screen is breathing a bit, nothing I can't handle but it is something of note.
I hope you feel well.
