It wasn't Me
Yesterday I wrote about being tired and having an early night. Early it was, but that counted to nothing when my stomach contents decided they didn't like the location.
About 1 am, up they came, and bed is where I have been ever since. It seems a virus is going around and I caught it big time.
In fact a day off work may well be a blessing in disguise, probably needed the break, but not the cause.
As I write this now at 8:30 pm, I feel fine, so the bike ride tomorrow is a good chance. Must drink plenty tomorrow, dehydration on a hot day after not much today must be countered.
