What's your excuse for not being out riding right now?

Hmm, that's the kind of stuff I found when I googled the symptoms. I've been putting off going to the doctors because I'm worried they might say something like that, guess I'd better go next week :(

On the plus side I am generally feeling better, presumably diabetes or whatever wouldn't come and go?

Thanks anyway Henry.

I would pop into your local pharmacy tomorrow or A&E and see if they can do you a sugar (prick)test. If you are diabetic you need treatment asap not on Monday. Diabetes is either type 1 or type 2 and you need to know which one you may have. In the meantime, ensure you take enough sugars/carbs during your waking hours so you don't 'slump' like you have been.
