a few days ago i took alot of 4fa in the night, like alot more than i usually do, about 500mg spread over a few hours. During that night when trying to sleep i got quite bad paranoia as i had some visual disturbances and also audio hallucinations, kept thinking i could hear my friends outside. I had this all the next day quite bad, probably because i didnt sleep. Now more than 48 hours on ive had a good 11 hour sleep. Im still getting fairly strong visual distubances and what im most worried about i still keep thinking i can hear my friends outside. Could this just be some hppd (i think i had it before after heavy mdma abuse but it got better), i also read HPPD can cause audio disturbances too. Or are there any mental illness's this could be?
thanks
