Luckily my dad is type 2, and is lucky that it is diet controlled (If only he would do as told

One thing I would suggest find out if your NHS trust does free courses in Diabetes, we did one with my dad (6 week) and it was well worth the afternoon.
It covered what it is, drugs used and our group went to the local Tesco (most of group shopped their) and read food labels to shown what is best to look for.
