Hey everyone ! I am a 21 years old french guy who now have HPPD since 2 and a half months, who has been induced by a wild Methylone trip triggered by a very large dose of it. This trip included very realistic and vivid hallucinations during 10 hours. Since then, I have visual snow, little sparkles of light dancing around, some purple going out of nowhere, after-images. Not visuals but disturbing too are the sleep paralysis, out of body experiences, anxiety, panic attacks... I stopped caffeine since it gave me thoughts that doesn't sound like mine and stopped alcohol too. Visuals might get better with time, during the day when I'm outside I'm noticing nothing at all. Things get pretty bad when I lack of sleep though, so I'm very careful with this. I'm on this forum to seek advices... Hope I'll read you soon. Sorry for the mistakes, take care
