I'm probably more experienced with LSD than with any other drug. As of recently, I've found it works really well to take half the dose to start with, then the other half one hour later. It has all the mind-expanding / sensory / euphoric power of the full trip but half the inebriation and intensity. It's sort of halfway between a standard acid trip, and mescaline. You can be communicating with angels in higher realms of existence, breaking down your separation from the universe and dissolving your self into the timeless eternity of the moment, remembering you are God experiencing this one particular view of your own infinite manifestation... all the while walking around in public and holding conversations sane enough to not get arrested. It is awesome.
