Changes in sleep histogram and chin electromyography tonus with treatment of duloxetine. a First PSG for the patient after duloxetine, 60 mg/day, for 7 months. b Second PSG for patient after duloxetine 60 mg/day, for 2.7 years. c Third PSG after discontinuation of duloxetine for 9 days. d Fourth PSG after discontinuation of duloxetine for 37 days. Lines under the x-axis indicate episodes of rapid eye movement sleep. PSG, polysomnography; W, wake; N1–3, non-rapid eye movement sleep 1–3; R, rapid eye movement sleep; TIB, time in bed; TST, total sleep time; SL, sleep latency; WASO: wake after sleep onset; REM: rapid eye movement; SE, sleep efficiency; AHI, apnea-hypopnea index; EMG, electromyography
