Wally,
I joined the NNTP newsgroups when I was first diagnosed 5 years ago and learned from experienced diabetics all over the world on every continent. The advice that drove me early on was condensed rather nicely by Jennifer:

In 5 months I went from a BMI of 33 to 25. My A1c went from 10.8 to 6.0 and has never been higher than 6.0 since, with a personal best of 5.5 although if I were really determined I am certain I could do better, but there's a life balance to consider. By the time I saw a dietician one month after diagnosis, I contradicted all of her advice because I already knew what her suggestions would do to my BG. I had the figures to prove it.
I've been passing Jennifer's advice on ever since. I'm heavily involved with another forum, so when you mentioned avoiding insulin it brought another chap to mind. Chris turned up in November and was concerned because he had been following all the official advice. Despite this he had never got his A1c below 7.1. He was on increasing amounts of drugs and was approaching the max for both metformin and Glic. We gave him a little general advice and pointed him principally at Jennifer's advice.
He now has an A1c of 5.9 and has halved his pills intake.
I've been pointing T2s at Jennifer's advice for years now and everyone who has given it a proper go has had a massive improvement. Most are in the 5% club.
Once you throw away the NHS/DUK recommendations and start to learn for yourself with a meter, you never look back.
