No, not the BBC programme; my voice.
This week I had yet another parents' evening and it was really hard work. Despite having a bottle of water on my desk and constantly sipping it, I lost my voice a couple of times and by the end of the evening my throat was burning.
The following day my throat was still sore and I had a hundred children to teach. No chance to rest my voice.
On Friday I was beginning to worry that I'd done something terrible to my voice, which is, after all, my job and my hobby, and something I can't afford to damage.
Then yesterday, in the beautiful sunshine, I took daughter for a walk in Dunham Massey and whilst we were walking my chest tightened up, my throat went dry, I started coughing and then I started sneezing.
So I went to bed at 6.30pm last night and I'm currently tucked up on the sofa with a blanket and a packet of paracetamol.
There's still two weeks and one more parents' evening to go before the Easter Hols.
Maybe chocolate will help?
