Matthew, that document appeared on the first page of a Google search for Delysid, where it was the first result of 187,000 [https://www.google.com/search?newwindow=1&hl=en&source=hp&ei...]. I'd never heard of it until seeing the name in the comment I replied to. It's a one-off as far as my having others like it to send on. FWIW, as a retired neurosurgical anesthesiologist (38 years experience/age 70) on three antidepressants (lithium/Wellbutrin/Paxil) for life after four severe episodes of major depression, I found it (the document) as fascinating as you did. P.S. This: https://mattwie.se/ is very cool.
