On medication

Sitting across an oriental rug from me in his Providence, Rhode Island office, Dr. Peter Kramer seems like an unlikely proponent of controversial medicine. His office, on the second floor of one of those classic shingled New England homes, is a 20-minute walk from the campus of Brown University, where he is a faculty member. And if pedigree is any matter, Kramer, a graduate of Harvard College and Harvard Medical School, is certainly no establishment outsider.
