Hi Researcher!  As you mention, the community here is of the highest caliber.  As you mention the restlessness and discomfort of the long-form psychedelic experience, I suggest you read Leary, Alpert, Metzner's book.  It uses descriptions from the Tibetan Book of the Dead to show these, and many other symptoms, relate directly to ego-loss, and they actually disappear (or become irrelevant) once one learns to let go.  EJ Gold also does a wonderful job (using a language clearer to the occidental audience) in his American Book of the Dead.

Awesome to meet you, be cool, be well.
