Spoiler Alert - Enjoy the diarrhea
Good news - you too can enjoy a capsule that is basically caffeine and vitamin B for only $1.24 each.  Does it improve your memory?  Well, you will certainly work hard to remember the closest bathroom.  So, maybe, yes?<br /><br />Save your cash.  Grab a coffee.  Read a paper\ink book instead of screen time and you will likely have much better results.
