Hi JConnor!
You say you were diagnosed Type 1 about 4 months ago? Are you actually LADA/Type 1.5? If so, your pancreas will still be producing some insulin (probably no 1st-phase, but a diminishing amount of 2nd-phase). Until the condition fully-progresses to Type 1, your insulin requirements will keep changing. I've had LADA for more than 3 years now and I am still producing some 2nd-phase of my own. As the 2nd-phase diminishes you will need more insulin - both basal and rapid-acting. You might have already progressed to full Type-1.
OK. Next, I find that different parts of my monthly cycle have a huge impact on my insulin needs. Hormonal changes affect insulin sensitivity. I believe it is high progestorone that makes us less sensitive to insulin and high estrogen that makes us more sensitive (but I might have that the wrong way around
). Anyway, the week to 10 days leading up to my period means I have to increase both my basal and my rapid-acting:carb ratio significantly. As the period starts, I have to reduce my doses quickly to avoid hypos. Many Type-1 women find the same. Also, pregnancy can cause a lack of insulin sensitivity - is there a chance you are pregnant? The same is true of various forms of contraception - have you changed any of these recently?
Finally, rapid-acting insulin has to be matched to the number of carbs you are eating - this is essential, not optional. You must count the carbs in the food you are eating and take the rapid-acting appropriately. As a very, very rough rule of thumb, 10g of carb will raise your BG about 3m/mol and 1 unit rapid-acting will reduce your BG by 3m/mol, so you should begin with a starting point of 1 unit rapid-acting for every 10g carb in your meal and adjust it from there. (That's a 1:10 rapid-acting:carb ratio). Buy a book called Calorie, Carb and Fat Bible. It is available from Amazon and details the carb in most of the food you eat, so you can calculate roughly how much is in your meal. I got started with this straight away and did not wait for the medical team. It is a lot to get your head around, but if you wait for a DAFNE course, you might wait a very long time.
Just so you know, I limit my carb intake to around 50g a day as I find my diabetes much easier to control safely without a lot of carb. You will need to assess your diet for yourself, but most diabetics have to reduce their carb intake to some extent to achieve stable figures - even if they are on insulin.
Take care
