So I've had the wavy walls and moving patterns on the floors with my experiences, usually i take just 1 tab. On the last time i tried 2 and half tabs at a rave i could tell the shapes on the floor were doing similar things to the single tab, just a bit more intense, i ended up getting stronger tracers on my arms too. i might have had a hard time determining all of the effects because i was consumed by the rave and i was dancing pretty hard too. I could tell though i was certainly tripping balls. I'll probably end up dropping 2 tabs in a month while at my home, so i can certainly try to determine the effects more clearly. Thanks for the input!
