Tired

 I had a terrible night of sleep last night, I couldn't get comfortable, I struggled to fit on a shared single mattress and I woke every 2hours or so with a very dry mouth and the feeling of a blocked nose. Then I spent today completely exhausted, with a headache and a sore throat. Symptoms that I suffer often enough that I'm pretty sure it's not Covid.
Tonight, as I prepared for bed, I realised that the ritual I have developed has a certain amount of superstition associated with, all of my actions are aimed at avoiding a night and day like I've just had. Here's hoping that;
A glass of water to stave overnight dehydration
An anti-histamine in case it's allergy that gives me a blocked nose

Careful flossing of my troublesome root canal/possible sinus problem tooth

Teeth brushing seems to help avoid a dry mouth too

Asthma preventer to make sure I breathe as well as possible
Nose saline spray to clear out my sinus before bed.

I'm not sure what will work, but I'm willing to do them all if it means a good night's sleep.

EDIT: Woot! 7 hours straight without waking up and then another couple of hours after that.
