So far, I do feel a greater focus and alertness, as well as less need of sleep.

I take 5 capsules of Focus first thing in the morning on an empty stomach with water. I then meditate for about 40 minutes. Since I started using this product I have noticed that it is much easier to maintain my focus on my breathe while meditating. I also don't need much time to 'wake up' my brain after waking. I notice a much easier transition into my work in the morning. I do not get jittery or feel anxious on this product even when I take it on an empty stomach (sometimes but I drink coffee on an empty stomach I get uneasy). I notice that it doesn't have any noticeable effect on my sleep.

So far, so good! Haven't had any adverse effects, but also do not notice any particular increase in mental faculties yet!

It is clear that this product contributes to my energy and productivity with some possible boost in focus. I do find that I want to take higher doses than the general recommendation of 5 capsules. So far I like 5 upon waking and taking 4 more with afternoon meal. I would try more but bottle says not to exceed 9.
