Okay guys after using deh's tip on the L-theanine, I added it to my mix and it has been the best thing I have ever done to this stack. So current morning stack is : 1) Focus XT (Caffeinated) 2) Piracetam 3) TMG 4) L-Theanine. This not only keeps my mental abilities high but my mood is rock solid and I have a sense of well being most of the time. The L-theanine seems to have converted the nervous jitters from the caffeine into an energy that is more exciting than nervous, so that has been blast. I tried noeept but it seemed to have made me a bit cranky and like I was in a funk. I still have the caffeine free Focus and will be saving that for nighttime when I need a boost. Great job this is the best stack ever, and I finally feel it is a match or better than the original Black Star Labs Go!
