Hi Skeg,
Basically a week off work (and employers are obliged to let you take it but NOT as holidays!) - hope you're not self-employed! You learn about how to calculate carbohydrate content of foods - the little books you get are very handy, I'm on my 2nd one as they can get a bit dog-earred! You also begin to experiment with your own needs, as each person is different. For example, you may find that you need more insulin in the mornings, less later in the day.
This helps you to establish working 'ratios' - that is the number of units of (in your case) Novorapid for each 'Carbohydrate Portion' (CP) - which is 10grams of carbs.
There is a lot to learn, and a lot of trial and error, but you do find that it gives you much more freedom and control. Personally, I feel pity for Type 2s these days, since diet is vital to maintaining good control. With DAFNE, you do end up checking your blood glucose levels a bit more, but for good reason.
You should also have access to trained staff in case you have any questions at a later date, and there are often 'refresher' days available too.
Ask your diabetic nurse, GP or consultant. If it's not for you then no-one's going to force you. But you might find it works a treat, and what have you got to lose, apart from a week off work?!
Hope this helps,
Rose
