When a small bottle arrives in her mailbox from ''Lewis Carroll'', Ayelet Waldman is at rock bottom. Her mood storms have become unbearable; she has tried almost every possible medication; her husband and children are suffering with her. So she opens the vial, puts two drops on her tongue and joins an underground but increasingly vocal group of scientists and citizens who are successfully using therapeutic microdoses of LSD. As Waldman charts her experience over the course of a month - bursts of productivity, sleepless nights, a newfound sense of equality - she also explores the history and mythology of LSD, the groundbreaking research on the drug and the Byzantine policies that control it.

Drawing on her experience as a federal public defender and a mother of teenagers, as well as her research into the therapeutic value of psychedelics, Waldman has produced a book that is eye-opening, often hilarious, and utterly captivating.
