Today was a little less impactful than yesterday but I could still notice effects shortly after using it. One thing I left out about Day 1 - which may have had an affect on Day 2 is that I felt intermittent energy spikes after the initial focus activation. In other words after I initially started to feel the effects go away and became tired, I went through a few bouts of random energy that kept me up.
This all led to me sleeping less than I typically would. Since I'm just getting into the trials for nootropics I'm not sure if this a common side effect of all nootropic drugs or the first two that I've tried. So far it seems as if trying the drug does effect sleep patterns in a general way.
