I'm sorry but I'm answering here since it seems very silly to post the answer in another forum.
Claridge,
You are lucky to be offered a course, many people who want to go on one don't have one in their area.I have never heard a bad report of a DAFNE course or a person who has regretted going on it. It is not designed to promote any sort of diet. Indeed it has been condemned for not promoting 'healthy' eating. You have chosen to use a low carb diet, for now. You have low insulin needs but at the moment (0nly 4 months after diagnosis) you are probably still well within your honeymoon period so you have some pancreatic function remaining.
Unfortunately it is most probable that eventually, your insulin needs will increase. People who have no or very little beta cell function still need to bolus (albeit in small amounts) even for a very low carb meals. I assume that you are not cutting out fruit and veg completely so you will be eating some carbs. Its worth learning to count these accurately and how to bolus accurately for them. Most people need to bolus even for a no carb meal since protein will convert to glucose. Learning to use insulin to mimick (albeit inadequately) your pancreas must be a useful skill.
Even if you think that you have adopted a lifetime diet It is just as well to learn how to adjust your dose for all eventualities. Even type 2 people who low carb tend to relaxe their diets for holidays like Christmas, its difficult not to, but a slight change in your carb intake at such times could result in soaring blood glucose levels. The info on the Dafne course will help you adjust.You can decide where to draw the line , some Christmas and party foods are very high carb. I don't eat low carb, nor do I eat Christmas pudding
).
You will also learn what to do with your insulin if you are sick and cannot take in solid food, how to adjust your insulin for exercise etc.
I'm not sure of your age ( I think you're female) but the tools you acquire will be extremely useful if you ever become pregnant.Very low carb dieting is not normally advocated in pregnancy and breastfeeding. If you ever want to use a pump a Dafne or other carb counting course is a prerequisite.
Finally and for this I'll probably be hung drawn and quartered. You may learn that a type I that does a reasonable amount of exercise can control their BGL without needing to take vast quantiites of insulin and yet be able to eat a diet that includes a reasonable quantity of 'good quality' carbs.
The other really important aspect of a course like this is also getting to meet other people with type 1 .It is really good to be able to share experiences face to face.
Having written this I have one caveat, I don't know how long the waiting list is in your area, or if you only have one opportunity to accept. If possible it might be better to go on the course when your 'honeymooon' has finished so that you can work out more realistic carb ratios.
