Hello MickyD, welcome to the forum. Did they put you on medication, or give you advice, or have they just left you to stew for the next month??
Let us know a bit more about your diabetes... How did you come to be diagnosed? Is there a family history? Have you been told anything about diet, and carbohydrates in particular? Do you need to tackle a weight problem?
Sorry to fire questions at you, but there are lots of us here with all sorts of experience. My own relates to controlling my blood glucose by losing shedloads (technical term for 6 stone).
