Thanks, yes it is a bit scary and complicated; when the lovely nurse was explaining, I said oh, so, his 10 minutes per hour, if he goes to the loo, I put in his eye drops (which need a few mins between each) - oops, can he then eat?! And she said, well, you will have to work it out quite carefully
He had the paracetamol then admitted he might need something else, so he had some ibuprofen before bed, and I've taken the paracetamol up for if he needs them in the night. Hopefully he's so exhausted he'll just sleep.
Loz I was saying to his mum it's a bit like your sudden deafness, although hopefully won't have such drastic long-term effects we just don't know at the moment.
