Hi there
This is a problem that many people face - their own area doesn't do the course. It is generally NOT possible to go elsewhere to get the course because each PCT (primary care trust) pays for it out of their own budget, so wouldn't take someone else's patients. I believe it's a travesty, but there you go.
BUT there is hope. There is an online version of DAFNE (link below) which is good. Be careful as you work your way through it, though - it is easy to miss sections and get confused. It certainly introduces you to the basics.
It might be worth giving this a go, though: the basic position is that you need to work out how much insulin your body needs to deal with a certain amount of carbohydrate. A good place to start is to aim to have 1u of your rapid acting insulin for every 10g of carbs you eat. This sounds a hassle, and you will need to get scales, but it WILL work. Food packets all have nutritional info these days anyway. So, if each slice of bread has 15g carbs, and you have two slices, have 3u of insulin. Start off on this ratio, test before and after each meal and figure out if you need to tweak it.
There are also a LOT of books out there about using insulin wisely: have a look on Amazon and buy a couple (it's likely that some are better than others). This will give you something to go on.
Also, seriously consider at least cutting down on the amount of carbs you eat. Although in theory you can shoot for what you eat, this is difficult. Cutting out some carbs from your diet will probably help.
Anyway, the link is below and good luck!
