I used to refuse sugar a lot. I once became hypo in a supermarket and refused to eat the strawberry cake my OH had bought (the only thing I’d agree to, probably as it looked delicious) until he’d removed the strawberry, eaten the jelly and put the strawberry back on.
I never become violent thank goodness, but I am rather demanding. Once I came round in the middle of the night, my kids were in hysterics because I had (apparently) been insisting my OH go and stand outside the house with a sign round his neck saying ‘It’s all my fault’. It probably was of course.
