Sorry I thought you were talking about doing them at the same time. But you do get a short trip from nitrious but Im not sure why, probably from lack of oxygen I imagine.
It is a dissociative and thats why you get "trippy" effects when you huff a balloon down real quick. You will experience heavy tracers, heavy audio distortions referred to as the "wah-wah's" and possibly out of body experiences. It is not from the lack of oxygen.
i sucked a balloon down and i felt like i was peaking into heaven, it was like everything was sychronized
i LOVE nitrous, but i don't think it's all that great on its own (i'm talking food grade, whippits)... but stoned/tripping it amplifies it SO much, in a really trippy way... taking a whippit stoned is pretty similar to tripping in some ways. i always find that nitrous gives me this feeling of total understanding (like, i'll have the sensation of my mind moving front to back and everything seems to make sense like this), and the next balloon adds to that (suddenly my mind is moving up and down, as well as front to back), and so on to the point where each whippit builds on all of the ones previously in a really linear way, and as soon as i come down i'm just going "oh i'm SO close i need to take another one immediately". hippie crack for sure.
EXACTLY i feel like i make the most deep mental connections and feel like i have figured EVERYTHING out, then it slips away really fast, so i crack up another one thinking im gettting closer and closer this gas blows my mind and im talking when im straight sober
