Query: A new tonic for insomnia

My wife found a damaged copy of Confessions for a few dollars, and bought it for me as a joke. She and I have both laughed for years at Jancis' smarmy tone in her column in Wine Spectator, though I also found her very knowledgeable about wine. Writing about herself rather than wine, Jancis has lost any sense of what the reader might possibly care about. It is the single most boring book I have read in my life, including chemistry textbooks. I seriously use it to fall asleep at night. It puts me out cold in 1/2 page, on average. That's worth a star!
