Patricia LaChance, who lost her husband due to opioid-induced respiratory depression, tells her story on The Doctor Weighs In.

John suffered from sleep apnea, which John and I thought at the time was merely a sleep issue. We had no idea it could also be a fatal issue. John underwent two surgeries. His first was a same day surgery. After this first procedure, he experienced a great deal of trouble recovering from the anesthesia. He struggled for hours to wake up enough to be able to leave the hospital. He was very groggy, nauseated and dizzy.
