Slow Down

Driving home from our holiday, I kept getting a feeling to slow down, but I ignored it.
We got caught behind some slow traffic on a country road that stretched for an hour. I patiently stayed in line. Once we got into the city, every traffic light we came to was red.
Later, on the motorway I stuck firmly to the limit. But I still had that feeling to slow down a little. I ignored it again, I wasn't breaking any rules, it was a relatively clear motorway and I was more than a safe distance from the car in front.
As darkness fell, I began to feel a little tired. I asked my daughter for three pieces of chocolate, thinking the sugar would give me a lift.
Not long after I began to experience a tingling sensation run down my forearms, blood rush to my face and spells of dizziness. There must have been gluten in the chocolate.
It had started to rain, it was dark, there were no street lights and I began to feel disoriented by trailing lights in my vision.

I was desperately looking for a lay-by but there were none. I was quite concerned, my daughter and dog were sitting in the back seat and I was experiencing the onset of losing consciousness.
Reducing my speed by 20 km below the limit I stayed in the slow lane and composed myself.

It then dawned on, we had been slowed down during the first leg of our journey being caught behind slow traffic, then the second part in the city by getting every light red and now this on the final leg.

I promised that if the unpleasant and dangerous dizziness passed I would do the rest of the trip at 20 km below the limit.
Fifteen minutes later the feeling passed and we later arrived home, and safe.
