Hi Lucie,
I have experienced similar symptoms but I have always thought of the denial as being a symptom, it's linked to the confusion you sometimes get? It's happened to me twice I think, I was at my hairdressers with my sister once and my right eye was twitching and I wasn't answering questions, so just appeared rude I think, but I managed to pay and went and sat in the car (I know, I know, INCREDIBLY dangerous!) but I didn't start the car, instead I ate some sweets which I kept in the glove compartment? so even though I was unable to tell anyone, I still treated the hypo?! Does that made sense?
