While it seems interesting, I have no idea how one gets a trustworthy supply of such micro doses, not to mention that fact that LSD is a schedule 1 drug. Caffeine seems much easier to obtain.
[REDACTED] acquired LSD tartrate, made solution w/ everclear, and then diluted it such that one sip is roughly 4-8ug based on volume. That's the only real way to microdose yourself, although you could cut a tab into 20 pieces (depends on the lay but a skilled lay is evenly distributed. An unskilled lay will have massive hotspots and thus one would need to dissolve the tab in a solvent or cut it into n->infty pieces)
