It is early days still so I am keeping an eye on what is going on, some of it is down to a change in diet but some is definitely down to the insulin.
You do sound like you hope that once it is sorted that's it, it's sorted. I hate to burst your bubble, but insulin doses are never sorted and fixed rigidly. You will get it right and it may stay right for maybe a couple of months and then something will happen and you may not ever know what that something is, but you will have to tweak and change it again. So it's not like "I am keeping an eye on it now because it is early days" you will always and forever have to keep an eye on it.
I'm just going through a period now where I know it's not right, but I am unsure as to where to change it. Or if it's even worth it right now as my circumstances are about to change radically and I might as well bumble along and fix it then.
I realise I will be juggling numbers for the rest of my life but as I like my life it is something I am happy to do.
My attitude to my health is somewhat different to others while I am aware of the long term I am working for the short term as well, it is a bit like the old saying look after the pennies and the pounds will look after themselves. My body has been trying to kill itself in various ways for decades and there are a number of things I have to monitor and adjust on a daily, weekly or monthly basis. I know i have various things coming up over the next 6 months which will probable change a lot of things but I will worry about them nearer the time. For the moment I have set myself a target of getting most if not all of my pre meal readings below 7 and I am getting there.
Over the previous 6 months my average BG has been in the region of 14 with only one reading below 10 and that was 9.9 which made me feel a lot better at the time. Over the last 7 days my average BG is 9.8 with a number of tests under 7 so things are changing which is good and making me feel better in more ways than one.
I have just upped my morning dose to 9 units so we will see how that goes once I get it down to a more acceptable level I will start testing as per the page you mentioned before which seems like a very good way to do it.
I am still having spikes after meals so I am updating my carbs spread sheet so that it is more accurate anticipating that I will be going on bolus sooner or later.
