I rarely change out of my mindset without something fairly powerful affecting me. The time I tried Adderall for a week or so I became a bit maniacal. I prefer not being that way, even though it felt awesome, as it made for too much collateral damage.

What sorts of thoughts cross your mind during said fleeting/shallow moments? I have a similar deal, usually lasting around half a second to three seconds, and once it's gone I end up trying to chase the feeling so I can understand it better, but just like that... it's gone.
