Experiences - is it possible for lsd or other psychedelics to last for days?

[qbarat2]

SWIM would like to know if anyone knows or has heard of any specific psychedelic that can last for a period of approximately 32 hours. SWIM took 1 paper hit of what SWIM believed was lsd, only to spend the next 32 hours thinking SWIM had lost his mind . Could a very high dosage of lsd cause the effects to last longer than usual or does the dosage just increase the intensity but not the duration? SWIM even went to sleep and woke up with the same intensity as before. SWIM has taken lsd many other times but this experience was extremely different, emotionally scarring, and life altering. SWIM's girlfriend also experienced the same results.

SWIM would like to tell the entire story to find out what it was, but according to forum rules asking this is not allowed, so SWIM will limit his question to asking if anyone knows of a psychedelic substance that can last for this length of time (approx. 32 hours), so SWIM can begin his search there?
