Hi Jilly,
I would also say that less than a week is too soon to see results. Most importantly you say your levels have improved - that's the most important thing. One thing I would like to add, is to suggest a book called the Diabetes Miracle by Diane Kress (I found out about this book from Brunneria and really wanted to try it as I was suffering from dawn phenomenom). I wish I had found this when I was first diagnosed cause I've been following it for about a week and I've seen really great results. I don't need to lose much weight, so I've been focussing on my levels and I'm very impressed. Prior to this I was following low carb high fat, which works but the principles in this book are slightly different. She talks mainly about the liver's role in diabetes and if you don't feed your body enough of the right things, your liver will intervene and actually make you gain weight - it's very interesting! One of the key things is to eat an hour within waking and an hour within sleeping and I've found this really helpful. I also learnt something really useful about alcohol. I always thought that alcohol helps with morning readings but have realised this could have been my downfall. If I have more than 1 glass (you are allowed 5 fl ounces on the plan), it actually causes dawn phenomenom. There is a piece about this in the book and it's really interesting.
Also, exercise is very important, just walking to start with.
Hope you find this helpful, look forward to reading your progress x
