i was abusing DXM (dextromethorphan) recreationally for a year and unprescribed pregabalin for a few months prior. i stopped pregablin cold turkey, then had huge amounts of the cough medicine (not 1-2 bottles per week but like 2-4 per day) during the withdrawals and then eventually the DXM and the pregabalin combined. i had the worst panic attack ever i was seriously convinced i was dying there was nothing like it. all the hospital could do was give me intravenous electrolytes, it took hours and hours to calm down and even then i noticed the top of my head felt weird since. i felt like it had been turned into a rock or bone or stone. as of august 2026 it has either stayed the same or gradually improved but not gone away, despite sobriety and intermittent fasting. I also notice that i cant physically cry, i feel a bit of emotional bluntness, and numbers/words/letters/concepts etc have this "mechanical" feeling to them and i cant stay askeep for more than 1-6 hours at a time
