I'm so sorry you experienced this. It is SO HELPFUL for you to share this experience though, since a lot of folks out here on the listserv underestimate just how horrible it is. I hallucinated too after they spiraled me up from the coma. I remember everything in the coma but it was complete nightmare. I would doze off and they wake up to a solid blazing white light followed by spinning psychedelic patterns and all I could hear was screaming, screeching tires, terrible traumatizing sounds. I wanted to die so badly but I did not know where I was and assume I was in H*ll or worse. So, it is really helpful to hear about your experience. Back in 2012-2015 time frame when we both had our dissections, there was a massive amount of opioids used for sedation. When I left UCSD I left the hospital NOT KNOWING I was addicted to opiods and had never ever taken one before. I don't drink or take any drugs of any kind, so I spent more than two months going through withdrawals and thinking it was the effects of two open heart surgeries. I think there should be a federal law that requires hospitals who give people opiods of any kind to give a complete written disclosure of what opioids were administered and the precise amounts. I stopped taking everything cold turkey when I left the hospital. It wasn't until a year later when I read every page of my 1,300 medical records that I realized I had been given a massive amount of different opioids when I was in surgery and in the 3-week coma. It would have been invaluable to my wife and kids to know why Dad was in bed all day, puking, not eating, and hallucinating because he had been unwittingly addicted to opiods. I went through almost 2.5 months of withdrawal without even know I had been given opioids. When I was discharged they gave me 240 Oxycodone which I promptly refused since I do not take drugs and assumed I could take Tylenol if the pain was too intense. Boy was I wrong. I hallucinated, had the shakes, had the sh*ts, puked constantly, couldn;t eat since everything tasted like metal, lost 60 lbs, was depressed, was in a complete opioid fog. So, I learned just how bad addicts have it when they detox cold turkey. Now, I understand that they saved my life, but they failed to tell me that I was going home to an opiod addiction with my little kids 3, 6, and 9 years old at home. Think Trainspotting (the movie). Here a list of exactly what they gave me when I was unconscious and never once disclosed to me after I was discharged and sent home in a wheelchair. I read all of my records a year after the surgery and found out:

Dilaudid
Haldol
Fentanyl
Remifentanil
Midazolam
Morphine
Naloxone (14 doses)
Narcotic Cocktail Drip (Google this)

So wonderful you survived it 🙏 yes anxiety and worry we have to live with unfortunately. Hugs of strength💗
I have fibromuscular dysplasia where you get aneurysms and strokes, had a TIA. I live alone and therefore afraid that I won't have time to raise the alarm myself and that my pets will be alone for a long time. There is nothing to be done, but you certainly get worried.
