Hi Sal,
I know exactly where your coming from!! This was my first ever clinic where I didn't get exactly the same reaction that you described. It's horrible. I'm sure to them it sounds so easy!! I've just started a trial of lowering my carb intake and seeing how I geton with that. Fingers crossed. So far so good anyway. I know it's easy for me to say to you but I promise you, I know what it's like and try to keep positive. We can't keep letting them win!
If you ever want to talk, feel free to PM me.
Take care
