Andrew W. reviewed Qualia Focus
Love the product but when it wears off you feel cloudy.
Focus without being wired
Not as much energy as with other products, but that is good in a way. Great focus, but doesn't keep you up so you also have to have a good sleep habit.
Improved clarity
Perhaps a mild improvement in alertness and clarity. My main symptom are trouble with word finding and memory and it was not helpful for those, and caused me to feel a little jittery.
