Hi Funnygirl,
My dad was dx with type 2 diabetes 14 yrs ago at the age of 51.
He also was not over weight, not a drinker, good diet etc so it's probably down to some get it some don't.
In the first 10 yrs it was controlled very well, just with diet and metformin. The diabetes did get worse however, and the tablets were upped and then upped.
In the last year he has had to go to insulin injections. Trial and error but is now on the right dose and is doing very well. He still works in the City btw and commutes 300 miles a day.
Read up on diets, join the Diabetic society, talk to the diabetic nurse and get all the knowledge you can.
Look after yourselves :D xxx
