Okay two things:
1 - this is a very interesting speech. listen to it:
in summary, this woman took (low-medium?) LSD daily and noted a increase in concentration, mental clarity and creativity. there's logic behind it, explained in the speech.
2 - a quick google for "daily lsd" shows a trip that pretty much backs it up. keep in mind his "lows" may be explained by the dip in glucose level. again, it's explained in the above pretty clearly.
