In the past I've had very low levels of B12 and iron a few times. Usually I knew it was happening if I got tired quickly and sometimes dizzy. I was also very thirsty most of the time, but I never told my doctor. I was used to it, so thought that was just me.
Blood got tested, turned out I had diabetes. Diagnosed in October 2004.
At first my doctor didn't want to give me medication, but my dietrician told her to get me pills immediately, since my diet was fine. Had been for years and still is.
So when I went to London to see the Moody Blues in the Royal Albert Hall I was on pills for only a short time. Was really weird...it makes me remember the month at least.
