My experience with LSD in my 20s was about as far from "micro" dosing as you can get. With that in mind, I found that while I did have some truly profound experiences, most often it was more along the lines of wasting time having fun. And things that seemed really deep while tripping were obviously and unambiguously superficial afterwards. From various experimentations over the years, the only drugs that make a real positive difference in my cognitive function are caffeine (in large doses) and alcohol (in small to moderate doses).
