Hi Hilary52,
I saw your other post earlier on today, is this the first time you've done carb counting this evening? I put up a post but it got deleted as my internet timed out. I was just saying that 1u to 10g works for a lot of people and is a good place to start but it's not the correct dosage for everyone. In the mornings especially if I'm very tired I will use 1u to 5-7g depending on what I'm eating and what my bg is. The rest of the day I'm 1 to 10g but occasionally when my hormones play up I will only need 1u to 20g. It can take a lot of trial and error, don't be put off though, knowing how to carb count and ratio your insulin will give the best results in the long term. Also it may be what you had for dinner if it contains a lot of fiber or fat etc it can slow down the release of carbohydrate so some people then like to split their doses to solve this. Hopefully you are feeling better now. Good luck
