"A&E Visit"

I'd already had ibuprofen an hour earlier, prior to the ambulance arriving, they then give me 2 more ibuprofen and 2 paracetamol tablets, and in the A&E department, I'm given codeine, within the space of 2 hours, I'm sitting in the waiting area for an x-ray, and

I start to feel drowsy, and I feel like I'm going to drop off from the wheelchair and lose consciousness, while the medical staff are just walking by. In the end i gave up and left, since the last 24 hours, the hospital has been calling me to check whether I'm still alive or not. I'm surprised that they'd even noticed I'd gone.
