Thank you guys, I have been diagnosed as having diabetes, so it is now just a matter of controlling it, albeit my tests results quite high.
I was having difficulty walking, which I had been putting down to overdoing the hashing, and quite a large weight loss, which poor Kaz is always having to battle with, I do nothing and it was dropping off me (last week was 5kg). But add to that feeling weak and tired all the time.
There is no history in my family of this, in fact my sisters comment was "I don't think I even know anybody with Diabetes". She does now
Just as an aside, I am so glad we took the SGK option when it was offered.
