I'm on long-active Levemir since yesterday. It's taken until this moment to get my prescription for fast-acting Fiasp. My blood sugars usually go down at dinner time and spike up 3 mmol/l 6 hours later with 12 grams of carbohydrate and nightly running, weights and the gym. Considering my fasting acting pen only has 1 unit doses (my nurse worked out I need 0.5 units for 10 grams of carbohydrates as my insulin sensitivity is sky high) I don't think I can use it tonight. Are there any LCHF diet type 1's on insulin who could advise? Also Bernstein said to take high powered short-acting insulins 20 minutes before eating or time it until blood sugars rise 5 mg/dl. I think Fiasp may fall into this category. Any advice on this?
