Hi
@pollyr
Like you I was eating to feed my insulin, I found 1unit of my Insulatard insulin would take me down by 2m/ml on my meter, its important to know how much 1 unit will lower your BS, especially if you are on a restricted diet to begin with, so when they moved me onto Novo-Rapid with my meals I first worked on the assumption that the Novo-Rapid would work the same and luckily for me it does, but it took a lot of testing to confirm this so be prepared to do lots of jabbing,
Now my daily intake of insulin is;
5 units Insulatard on waking........1 unit Novo with my breakfast
1 or 2 units Novo with my lunch depending on what I'm having ie: 1 unit if having egg and bacon
5+ units Novo with my dinner depending on meal
5 units Insulatard before bed
This works for me BUT you will need to work out your own unit to meal needs, so do test before and after each meal, and keep a good record of what you had so you can refer back to it and adjust your units if needed, it does take a few repeated tests for regularly eaten meals to get a good idea of units, but once you have this information you should be fine.
One more thing to remember timing of the "with meal insulin" is important too, but this will come with practice.......hope this helps..........please feel free to PM me if I can help further.
