After a lot of sleep and clear fluids I'm feeling much, much better today. I was even able to eat solid food - toast with honey and french toast - which means that I'm definitely on the mend.
Funny, I woke up a lot earlier than I thought I would because I had sweat so much in my sleep that my sheets were soaking wet - either I had a hot flash thingy or else I fought off a fever in the night. I hope that doesn't happen again - I now understand why menopausal women find night sweats unbearable.
I'm very much looking forward to going to Edmonton; I've checked in and printed my boarding pass and everything. I'll be sitting towards the front of the plane which will be nice for deplaning :)
