The strain you picked up must have been a sativa. Unlike indicas, sativas produce a very clear headed, europhic high. You won't feel the urge to nap like you would with an indica. Also, I notice after smoking a pure indica, my eyes are very bloodshot within minutes...most sativas don't cause your eyes to become as bloodshot as an indica would. Get a bottle of rhoto's, best eyedrops in the world.
