Peachy.

I have anaemia, plus B12 and vitamin D deficiencies, despite all the supplements I've been taking. The likely explanation is that the dodgy bit of my innertubes is becoming even dodgier, failing to absorb certain nutrients, no matter how much I gobble them. I have to go see the innertube doctor and take a jillion vitamin D tablets.

ETA: Oho. And for ten points, which medication used over the long term can cause vitamin D deficiency? Why, it's Questran!
