From the time I was put out until I awoke in the ICU seemed like an instant - like the quickest OHS in history! No dreaming, so sensation of the passage of time at all. And I awoke completely alert because they gave me a hit of Narcan (narcotic antagonist) to reverse the Fentanyl (narcotic) after I apparently stopped breathing. Kinda scary in retrospect, but I suffered no consequences, as far as I can tell. Fortunately, I NEVER felt ANY pain and needed no further narcotics or other pain medication at all. Other than the expected short-term post-OHS weakness, some temporary sleep disturbances, and a few weeks of partial gastric ileus from anesthesia, the OHS was experience was unbelievably benign.
