Only being diagnosed five years ago, I have no idea what you’re banging on about old-timers!
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!
