Nope never done acid, and honestly i had woken up at 1 and it was only 11 when this happend. The robotussin gel packs aren't time released or anything like that are they? I mean there's always an afterglow the next day, but that was just too wierd. Oh well, It was actually pretty cool, i love hallucinations.. it was crazy though, one point i was thinking "omg my uncle is Satan and i can see through his mortal "cover"".
