Nitrous alone gives me a slight head rush and a consequent headache... On MDMA things start to get a little interesting, but it's really the TRIPLE CROWN (a term coined by my friends) that puts nitrous in relief:

Ketamine (a fair amount of it)
Nitrous balloons

JBArk is a Mandelthought; a non-fiction character in a drama of his own design he calls "LIFE" who partakes in consciousness expanding activities and substances; he should in no way be confused with SWIM, who is an eminently data-mineable and prolific character who has somehow convinced himself the target he wears on his forehead is actually a shield.
