I went on a course (called something like 'self-management of diabetes') in NZ, and found the greatest gain to be getting a blood glucose meter on the state, and basics in how to use it. (I learnt the hard way about heating up my hands under warm water to get the blood flowing - lots of wasted test strips and error signs until my practice nurse told me. Note, I was not forum-ing then. If only!)
The other great gain was meeting other diabetics going through the same things face to face.
And, also, witnessing the complete disregard for carbohydrate intolerance in diabetics my country has (sadly!) - in person, from otherwise well-meaning nurses and nutritionists.
I also really liked the video demo of how the insulin and glucose was working, and not working - so I have been a diabetes-videos-on youtube-junkie ever since.
Didn't make any friends, alas, because I think I annoyed them with bringing up carbs. They all loved my paleo 'truffles' at morning tea though. (Seed butter, coconut oil and some other yummy filling things rolled into little coconut covered balls.) And one chap really appreciated my carb-count of alcohol sheet I photocopied for him. (He asked about whether we can drink alcoholic beverages - a common query!)
In Sweden, I also did their course, and the best gain from that was....being able to get a full blood count on the state. (There is a theme to this.) And, witnessing the health professionals complete disregard for carbohydrate intolerance in diabetics. (Yeah there really is a theme!) The big difference in Sweden is the nutritionist was skinny. (The only skinny nutritionist here I have seen is a LCHF one!) And the panel of doctors talk that I had been REALLY looking forward to was focussed on my cholesterol level - I was so disappointed and upset by this I cannot tell you. I really thought I was going to have endocrinologists (three of them!) focus on how best I could get better from diabetes, you know, with an in depth look at my hormones, and it turned out they were most concerned that I take statins. Go figure.
But, your course looks like you won't have the disregard for carb intolerance - yay France! (This truly is wonderful. As even though Sweden is famously an approving-LCHF country it did not spill over to my desmond-like course.)
My feeling is - you will get some great medical support that you might not otherwise, which will make it worth while. But have low expectations, and then you might be pleasantly surprised? And, be sure to write about it in here, as I for one am way-interested in how different countries do this!
. (As many others are, I am sure.)
Vive la France!
