just doing it this week, even though I have pretty god control, and am on low dose anyway, they've been very helpful in reducing these even further and getting the basal doses right.
I've now taken my basal dose down from 6 am and 8 pm to 3 and 6.
It's very narrowly focused and one of the dieticians here was being very rigid in term of refusing to answer certain questions and or preventing the class members doing so, so she was not getting the best value out of the knowledge in the room. Some of the sessions were pretty mickey-mouse in my opinion and my experience, with an assumption that they had to start at the lowest common denominator, so bear that in mind.
Overall though, any T1 should be able to get value out of it, even the guy on my course who's been T1 for 30 years.
