Woke up at WTF o'clock with a really severe pain in my injured butt-muscle and had to be really careful when peeing when I got up so that I didn't pass out from vagal nerve stimulation (I had to stop mid-stream and lie on the floor for 5 minutes until the darkened-vision and cold sweat eased off enough for me to resume; I've already got a scar from whacking the toilet with my face, and I don't want another one). It's hurting a lot less now thanks to paracetamol and a hot water bottle, but I'm tired and feel a bit sick from it.
