Some positive effects. Taste is ghastly, though.
I've been using Qualia for about a week now. The benefits are subtle, but approximately as advertised, with a mild increase in focus and drive. The seven pills that you have to swallow, however, are pretty large, and they have a godawful scent/taste that present themselves when they hit your tongue and mouth. By pill #3 I'm struggling to get them down. Dunno if I can endure this unpleasantness in the long term and become a consistent user.
