Thanks for the thoughts everyone.
Checked out of hospital Sunday 2pm. Home, sleep sleep sleep, every time I tried to drink let alone eat...vomit. more sleep, headaches, more sleep , more headaches.
So in the last 48 hours I've managed 1/2 a sandwich, a yoghurt (not a wise choice which was soon brought back with the sandwich. Even this morning a drink of water was summarily rejected by my stomach. Just managed some food an hour ago and drinking juice is ok now. Still have headaches.
I assume the amount of pain relief I had has upset my bodily systems, starting to feel a tad livelier on the plus side. Tomorrow sick again, no way I'm going back to work like this.
