Haha I'm actually really gettin into fooling around with Nootropics especially since starting my MPH program! So far I've noticed there are 3 routes you can generally go. There is a focus route by means Alcar, phosphatidylserine, Alpha GPC, i want to try out Alpha Brain by Onnit Labs as well.
I currently don't have expierence with the likes of piracetam, but I will also chew some nicotine gum for some added focus. The next realm of nootropics are the euphoric kind, PEA, Dl phenylalanine, dendrobium extract, be sure to add some Hordenine hcl for decreasing breakdown by way of stomach acid. And finally the third realm relaxation, 5htp, l-tryptophan, GABA, Phenibut, Bacopa monnieri (careful a gram+ of this and you can get couch lock:) ) Hope this helps and if you want I will post a list of how I stack / dose some of these!
