welcome to the forum Priyanka or can we call by your nickname pink?
I've done the DAFNE course, but to my understanding that most of the carb counting courses that other PCT provide are very similar to it, just less expensive to implement for them...
Here goes, the DIP course will give you the frame work not only to take control, because it will teach could monitoring practices, what you results actually mean and how you can use them to take action to determin the best way to make changes to your insulin to achieve good control..
Here you will find different ways to how some have managed to control there diabetes, as to whether you will need to go to the extreme level of carb restriction will depend on several factors, but once you've started your carb counting course you will be able to look at what works for you...
I hear a lot about how insulin means that you increase you're weight, but some of this is derived from myth, as for some people it is mainly caused by the simple fact that they are having too much insulin so end up having to fed the insulin that is swimming around there bodies with extra carbs and then wonder why they put on weight...
You will learn how to avoid this, and once you start to realise where the carb is hidden in a meal, and how many there really is in that meal, is generally a very good incentive to naturally cut back on portions size etc... So some of the work will be cut out for you...
What I would do now, is get some good monitoring before meals, 2 hours after and before bedtime, along side what you ate for that meal (inculding if you can portions size) any snacks or exercise you have done... This will help when you start your course, and also be helpful to your instructors as well to see what you've been up too..
