Yay Alphageek_gb!
I had a setback yesterday, and ended up in the ER.
I think what happened is that since I'd been sick with a sore throat the two previous days I hadn't drank as much as usual and so I'd started my ride under-hydrated. I looked up all the symptoms when I got home and they match exactly for dehydration.
Now I'm way behind on my miles but there's more than a week left in the month so hopefully I can get back on track.
