Very similar in manner to redose compulsion for N2O.
You feel that there may be something (or, better, Nothing) just around the corner if only you just tried one more time.
At least, that was my experience
well...feeling 'nothing' (actually no thing) sounds like a nitrous type pursuit...that aside, I wonder how that would play out with thousands of times nitrous's time-span.

It is definitely not like others in its class *cough*meph*cough* where you have the Rat-Lever Syndrome. [/QUOTE]
