Diabetes Type 2 - any dietary advice ?

Have just been diagnosed as Diabetes type 2,so does anyone have any dietary advice for me.One nurse is telling me to cut out all carbohydrates (potatoes,chips,pasta etc) and another is saying they are okay to eat ! I have also read that diabetic foods are no better (or worse) than ordinary foods including chocolate.Also,any alcohol advice,I don't drink that much but do like a good swish once every weekend.Any help/advice appreciated.
