Hi and welcome to the forum 🙂
If you want to feel back in control, you need information to work with! Gather yourself some data by doing BG tests:
- on waking / before breakfast
- mid morning (2-3 hrs after breakfast)
- before lunch
- mid afternoon
- before tea
- 2-3 hrs after tea
- before bed
- around 3am a couple of times a week.
Record all your BGs, together with a diary of food eaten, exercise done, and any other relevant info. (I'm assuming you are carb counting, but if not, start! The book and app "Carbs and Cals" is very useful for this).
Armed with this information, you then need to look at where in the day you are having problems with out-of-range BG levels, and look to make changes to the relevant insulin. For example (assuming you are on a basal-bolus regime), if there is no pattern to your BGs but they are all higher than target range, you could start by raising your basal insulin. Alternatively, if there is no pattern, but you are getting lots of hypos at different times of day, it would be a good idea to reduce your basal to try and eliminate the hypos, and then move on to focus on the ratios for each mealtime insulin dose.
If you are seeing a pattern of high or low BGs at the same time each day, then focus on that particular time, e.g. if you're always low before lunch, you perhaps need to reduce your breakfast insulin dose.
Unfortunately there is no easy solution 😉 - but studies have shown that there is a correlation between doing extra BG tests and a reduction in Hba1c - as long as you take action on the BG results, ie. adjust your insulin doses, take correction doses when high, prevent lows by having a small snack, etc. It is completely relentless, but you are not alone! Good luck 🙂
