Couldn’t understand why I went high after lunch & dinner & why correction doses brought me down so slowly - then discovered I’ve put a Levemir cartridge in my pen instead of Novarapid. I usually I inject 13 units of Levemir ( 7 in the morning & 6 at night) but since 14.00 I’ve injected 14.5 units. Even without tonight’s 6 units, that’s 8 units more than usual. I usually stay within my target range ( 3.9 - 7.8) through low carb diet ( occasional highs up to 9.0). Have been between 11.0 - 7.0 & now rising after dinner. Should I let myself run high and the extra Levemir will eventually bring me down (& not use any NovaRapid or do tonight’s Levemir)? Any advice gratefully received!
