Continuing from here, things have changed yet again. The good news is, the yeast is busted. Apparently I've been on such a strong dose of medication there can't possibly be any left. The bad news is, I'm still not better, so there are further problems. My doctor says it's quite likely that the yeast infection caused me to develop allergic reactions to foods. This isn't as terrible as it sounds, because if this is the case the allergies will be curable, unlike some other food allergies I have.

In order to establish what foods I react to, I have to go on a 6 week exclusion/diagnostic diet, starting tomorrow or Thursday. Here's an extract from the form I have detailing the first stage of the diet:

For 8 days you should only eat the following foods:

 

Lamb, Salmon, Cod, Trout, Plaice, Sweet potato, Broccoli, Parsnip, Mange tout, Carrots, Kiwi, Pears.

Use Olive oil for cooking.

 

No smoking, no tea, no coffee. Drink only bottled spring water - flat or fizzy.

You get the idea. It's very strict. I don't know what the diet starts adding after the first 8 days, but yeah. Apparently the first few days are kind of awful, because you get withdrawal symptoms.

Bring it on.
