I am in humlog mix 50/50. I find that my sugar levels elevate during day and after meals .
The 50/50 is a combination of short and long acting for between and after meals and is a great choice to handle a 14 hour period including meals
If you are still reading high both during the day and after meals you need your dosage increased
Show your Doctor your numbers and they will suggest a new dosage (unless you are dynamically adjusting your units yourself - then you should know what to do)
