I've just got back from today's visit, they've changed his med's and upped his sedative portion. He's very sleepy (hardly surprising given the drugs he's on) but the change has helped him breathe a bit more easily. He looked very relaxed today and he kept up with the conversation quite well, before he drifted off for a snooze. His partner is an emotional wreck, but she's keeping going remarkably well considering.
Oh, as soon as I got home I attacked 2 x wasps nests with nest killing powder. The foam spray I tried earlier seemed to work OK but after a week or so they came back. The powder is (alledgedly) much better, although I seem to be wearing quite a lot of it...
