Don’t even bother with crackers, they suck. Just buy a 1L+ tank and some big balloons from Amazon.
Also, don’t do it every day, or even every other day. You will fuck up your vitamin B12 reserves and you’ll quickly discover what happens. Having a binge once a week is much better for you than a couple balloons every day.
I’d also point out ripping nitrous hits out of balloons is most definitely abuse. Ain’t nobody out there using a regulator and metering their nitrous intake like medical usage.
No, I find DMT to be quite sexual. I took a monster sized hit while peaking on MDMA and it was like getting sucked off at a spiritual level. Not just physical sensation but that someone or something was doing it to me, like a psychedelic “nut and she keep suckin” into fractal infinities of sensation. Felt so intense it was kinda scary, like being taken advantage of by an ancient being. I’ll probably try it again sometime.
