Thanks for getting back with us to let us know you did well!
From here I’m interested in learning how to work out my insulin to carb ratio as when I inject 1 unit for 10g carbs my levels shoot up.
I would post about this in a new thread with a fitting title for visibilty if I were you.
Most of working out your ratio is trial and error, and log keeping.
You already started doing this without realising: "when I inject 1 unit for 10g carbs my levels shoot up" tells you you need more than one unit for 10 grams of carbs. If you know that, it makes sense to have your dose slightly increased and see what happens.
Being only recently diagnosed, you'll likely want to contact your diabetes nurse to ask if you can start some careful experimenting to work out your ratios.
Once you're in a bit longer, you'll be changing your doses as you see fit.
as my levels are always high.
If your levels are always high, you'll want to look at your basal dose as well. If the basal dose is off, it's almost impossible to get the bolus right.
Again, something to discuss with your DN.
It's also worth looking at timing. If you shoot up after eating, but come down again in a few hours, the dose was likely right but the food worked before the insulin. Many of us found we need to dose a while before eating.
Do you use a CGM like Freestyle Libre or Dexcom or only fingerpricks?
A CGM makes it much easier to spot patterns. The Libre also lets you log food and insulin, which makes it even more easier to see what's happening.
Good luck!
