Euphoria: 8.6/10, like meth with more love
Creativity/Insight potential: 2/10, not really special but can make thoughts manic & irrational

Norepinephrine: 8.8/10
Functionality: 6/10
Comedown: 4.8/10 (without abuse/binge)

Redose urge: 7.1/10, lasts about an hour orally and (for the most part) then fades. Be super careful if not strong willed!
