Any dopamine booster (agonist / reuptake inhibitor) has wildly different effects on different people. Or across different times in their life. Anecdotes are good to share, because they illuminate the variety of experiences that one should be prepared for.
Even Vyvanse vs Adderall XR are reported to have markedly different effects on the same person -- and after metabolic conversion, they're supposed to be the same active ingredient with fairly similar time release duration.
