Jeepers, glad to hear you came out of it ok the other side. (I'm assuming.) Always good for people to pass on such stories though, can't be reminded enough how powerful this stuff is that we're messing around with.
Yeah, I'm fine, thank you
I actually had the same thing but worse as a teen. I can't even remember why I was prescribed Codeine but I'd barely taken any (this was before I ever did any kind of drug). I was having SEVERE insomnia and remembered the Codeine made me feel sleepy so I figured I'd just keep taking more every 20 mins or so until I could sleep. I'd taken like 250mg when suddenly I noticed the hives and I had the worst itching I have ever had in my life, full-body. Like, I was bleeding all over where I couldn't stop myself writhing at my skin. My face felt weird and I couldn't open my eyes properly so I looked in a mirror and my face was swelling up, especially my eyes.
Suddenly I was so weak I had to lie down (right there on the bathroom floor). I was too weak to even raise my head and had to yell for my parents to call an ambulance.
The EMTs said I had the lowest blood pressure they had ever seen on someone conscious.
I saw no reason not to be honest with the paramedics and they gave me naloxone twice (they assumed it was an opioid overdose since I was opioid-naive and the maximum dose of Codeine is 60mg not 250mg) but it did NOTHING, so they actually ended up treating it as an allergic reaction "borderline anaphylaxis" is on my records since I started wheezing, too.
I was fine, but spent the night in hospital being given fluids and lots of antihistamines.
Oh, and WEIRD, but both these times I've described, I got EXTREME diarrhea. Both times every single medical person (paramedics, doctors, nurses) were totally flabbergasted that all that Codeine had me with extreme diarrhoea, not constipation.
I did finally speak to someone (a pharmacist) who was like "Oh, yeah, it's VERY rare, but I HAVE heard of people having diarrhoea from opioids". I continued to get mild-moderate diarrhoea the whole time I was prescribed Codeine. The DHC never did that to me and the Morphine I take now doesn't, either. My body just reacts really harshly to Codeine for some reason. It's on my medical records that I'm allergic to it, but also I was prescribed it (60mg, 4 x day) from like 2021-2024 so IDK what's going on with that.
