There was a statistically significant increase in fatigue and reduction in mood for the high dose combination group but not the low dose group. There was a statistically significant improvement in reaction time on digit memory recall but not an improvement of accuracy in the low-dose comnbination group.

There wasn't a statistically significant difference for sleep latency, digit symbol substituent, choice reaction time, sustained attention, immediate word recall, delayed word recall, sex-letter memory recall for the combination groups.
