Blimey!
Seriously, such a weird feeing.
I was at work today and a couple of my colleagues that were on my same shift yesterday said I'd looked not myself at all, out of it. They said I was chatty and friendly, as usual, but they could tell something was pretty wrong.
I can still smell the smoke thing occasionally today, and feel OK for the most part - like my best self. But then I totally crumble with tiredness and have to sleep.
