After you mentioned nerve pain I remembered I had some pregablin in my meds box. It's done the trick and dulled the pain.
I can't sleep. I have to be up for 6.30 to take my meds, walk dog and get my stuff together. Got to leave for 8 and get there for around 9.
Throughout all this I tried to adopt a stoic mindset. It didn't work. A stoic would say "A man who suffers before it is necessary, suffers longer than is necessary". I would say Seneca didn't have toothache.
