Felt a bit of an idiot today.
I have resolved not to eat chocolate or anything with sweeteners or drink alcohol for a week to see if my headaches stop, so went for a walk with a friend to get some fresh air but was so busy watching where I was putting my feet so as not to slip in the mud that I walked straight into an overhanging branch and nearly knocked my self out.

Have had a corker of a headache since, so might have well had the chocolate and wine after all !

Easily done, I have even done it standing up after weeding under the fruit trees in my own garden. Hope you are not bruised.
