although i found oxycodone much mroe physically and socially stimulating, I can vividly recall
my first semester at state college, I would pop 7 10mg vicodins at my GF's house then drive across the street to school, and once they would kick in i'd be in the library working out equations with such enthusiasm and vigor, and cognitive sharpness.
To any one, I highly recommend hydrocodone and oxycodone as a study/test drug..
I find this to be 100% accurate. Vicodin enhances cognitive sharpness tremendously. Gives an unbelievable amount of energy too.
