Driving while under the influence of

I realise this is a little out of left field but bear with me…
With an average of just 5 hours’ sleep each night, it’s no wonder that my nearest and dearest regularly labels me cranky. It’s true. For the most part, I am short-tempered, easily irritated and not a particularly considerate driver. Anyway, I have just renewed my car insurance but this time they’ll put a little black box under the bonnet/hood that will monitor how I drive and reward me for doing well. A rod for my own back? Ah, yes but with a Sofi spray to improve my sleep and an automotive carrot to encourage me, I shall be spared the stick. Quod erat demonstrandum? Hopefully!
