I changed my phone recently to a Samsung because the Samsung health app allows me to log meals and it gives me an outline of the main nutrients taken from meals based on the data input. I can also log blood sugar and, importantly, insulin doses. I did a rough calculation a couple of days after I started using the app. It worked out at taking one unit of insulin for every approximately 11.1g of carbohydrates I consume. I rounded off to 11g. So now I take one unit of fast acting insulin for every 11g of carbs plus one unit for every 2.5mmol I'm over 6mmol/l before a meal. The carbs for my evening meal the following day was about 40g - less than 44, more than 33 but closer to 44. So I rounded to the nearest 11 which was 44 and took 4 units for it. At the time of testing before taking my long acting insulin before bed my blood sugar had dropped to 4.1mmol/l. I allow for a drop of 3mmol overnight when taking long acting insulin. So this meant I had to eat before bed. Had I taken three units of insulin instead of four I would have been above 6.5mmol/l. I would have still taken a half a teaspoon of raw honey to prevent a low and stabilise my blood glucose but the point being I will always round down to the nearest 11g in future. Lesson learned. So, for example, if there are 54g of carbs I'll still take four units instead of five. I won't take five units until 55g or above to be sure.
This evening I had a Dr. Coys chocolate bar while out & about. But it didn't seem to affect my blood glucose. It read 5.9 before my evening meal. Here's where I'm getting to the point of the picture. The carbs for my evening meal worked out at about 90g this evening, warranting an eight unit dose. But I decided to give myself seven units because I didn't want to be below 6.9 taking lantus. With the 2.5mmol for every unit guideline I figured I should be approximately 8.5mmol/l taking long acting insulin. As you can see, those seven units left me at 8.6mmol/l at long acting dose time.
It really does seem that the help of this app will give me greater control over my diabetes over time.
