 1. Selection of subjects will be based on the patients exhibiting sleep disturbance as assessed by a standardized sleep questionnaire. Because we are also interested in the effects of MBBP on co-morbid illnesses besides insomnia, we will include subjects that are being treated for depression, pain, and general medical conditions, except as defined as exclusion criteria. Subjects using anti-depressants, sleep and pain medications, and other medications for any condition that is not under exclusion criteria will be admitted to the study. Thus our inclusion criteria will be broader than those based on DSM-IV for primary insomnia.
