Experiences - Nitrous and Head Rushes

[voodoo child]

Growing up, I've always experienced head rushes. You know, when you stand up really quickly after long periods of sitting. Usually, I'd just grab onto something and focus really hard, and it'd go away fast. And they didn't happen all the time or anything.

Then when I got in HS though and started to get high all the time, I started to appreciate head rushes as sort of a free high, and would try to ride them out as long as possible.

To SWIM, head rushes are a very similar experience to nitrous highs. Often times they're a little more intense and dangerous, because SWIM finds himself knocking over stuff and hurting himself, because SWIM can't control his body, and nitrous has always been something SWIM has more control over.

But are they in any way linked?
