Down in rural Gloucestershire, they run three courses:
Diabetes and You, Food and You and Insulin and You.
'Diabetes and You' is voluntary, but is 'Highly Recommended (or else)' by TPTB.
It is a primer on the mechanics of Diabetes: What it is, does, what to eat to make best use of your suffering, what you can die of etc.
Learnt- I must have breakfast (Useless, I can't face breakfast at 5AM when I get up for work) and I probably shouldn't pour condensed milk on my bedtime porridge anymore.
Value- 'Better informed, but no wiser.'
