That’s not wrong, but it ignores the effects of catecholamine metabolism and the co-storage of dopamine and noradrenaline in the same vesicles. Noradrenaline release necessarily causes dopamine release, but also an increase in the activity of dopamine beta-hydroxylase, which starts converting more dopamine into noradrenaline — hence the drop below baseline, discomfort and drive.
