Re: Fed up
Ahhhhhhh
The 100 rule works out a correction factor for you based on what your average total daily dose of insulin is (this is the basal plus the daily bolus added together). The idea is that you do a bg test and if it is above what it should be, you calculate a correction dose using the 100 rule and then write it down on piece of paper and then work out your insulin to carb ratio based on the amount of carb that you are going to eat and then whatever that amount is, you then add the correction bolus to the carb bolus and deliver the insulin in one injection. If you haven't done it as yet, do look up BDEC as recommended by others which will help you.
Most people start off with carb ratios using 1u to 10g carb and then test their bg levels about 2hrs later to see if their bg level is ok or is higher than it should be and then if it is, like above 12mmol, they deliver a correction dose so that they can get back towards their target bg level. Targets vary from person to person though..... my target is to try to be 6mmol before my main meals, then 8.5 - 9.5mmol 2 hrs later. Look at the NICE bg guidelines.
It is thought that most people will probably need to use 1u for 8g carb at breakfast time and then by testing bg levels every 2 or 2.5hrs, they then start to adjust the ratios to deliver more or less insulin so that they dont have to use a correction factor. It does take time to get everything ok probably about 1 week but definately use a good bg monitoring book, write down insulin doses, carb eaten and carb ratios being used....
