I am not the owl I used to be.
For as long as I recall, I've been a night person this did help when I used to chat with friends in the USA and Canada.
Being a night person could be the reason I didn't suffer from jet lag on my trips to Canada too, or it could be put down to my insomnia.
In the last month or two, my life has taken a weird change. The most significant effect is that as I don't chat online, I am no longer a night person; these days I go to bed on the same calendar day as I wake up, not the 24 hour day as before.
