Thanks Mrs D,
I am going to try convince him to be evaluated again by another doc, making sure that his insulin levels are checked out.

His doctor put him on metformin & was told to eat a low carb diet & not to drink anymore beer [ which he did drink a lot of ] but to exercise more which the [excercising more bit] just seem ridiculus to me, as he works a very hard physical job anyway.

Crikey, i guess a misdiagnoses like this could be fatal.

many thanks
Brian
