About a 1/2 hour after digesting the pill I began to feel the affects. I did notice a slightly heightened sense of awareness and focus. Since I spent the majority of the day driving I cant really say how much it influenced my other cognitive functions or allowed me to become dramatically more focused. However, I can definitely say the amount of driving I did yesterday would typically wear me out around the 2 hour mark and I was focused and attentive the majority of the 6-7 hour drive.
The affects began to wear off for me around the 6-8 hour mark but, I believe that had everything to do with me being exhausted from taking a long drive which is a tad mentally exhausting for me.
As far as side effects go the only real side effects I noticed was a very slight aching in my lymph nodes around the my neck and upper back area towards the end of the drugs activation.
