well i tried the nitrous today and it felt like the real thing or i guess whatever the dentist gives you when you go out to pull teeth, but then my friend said its not real and its just like a placebo, Instantaneously all the effects went away i felt normal and none of the doses work anymore

Thats the same thing that happened to me in that same order. I didnt really feel different though. The only noteable thing would be 3 or 4 laughs
