I had some smarties on Thursday. Quite a lot of them and they gave me a headache, which I put down to the sheer amount of smarties and all the crunching.
But I had a chocolate minimilk this afternoon and have the same type of headache.
Surely a mini-milk wouldn't be enough to give me a reaction, if that's what is happening? I used to get insomnia if I didn't have chocolate every day. What's become of me??!!
