Nightmare,
When my STBXAH was in the hospital for surgery, he was stark raving. I'm not sure if it was withdrawal, or maybe his liver couldn't process the pain meds, but he was totally off his rocker.
It was frightening.
He was fine immediately after surgery, but about 48 hours in is when the craziness started. I begged them to keep him longer, as I knew I wouldn't be able to control him at home.
Anyway - just letting you know that someone else has seen that too.
