Only being diagnosed five years ago, I have no idea what you’re banging on about old-timers! 
Welcome to Shoot Up Dave! I agree with what they’ve said above – DAFNE is a Good Thing. I never did a formal DAFNE course as I was essentially taught it all when I was first diagnosed. I just don’t know how anyone could get resonable control without it.
If you can’t get the time off work for it, there’s an online version somewhere. I’ve forgotton the URL, but I find it and post back. It might be a useful start.
Anyway good luck with improving your control. My motivation for doing it is not to please doctors but to feel well as much as possible. Woo yay!
