Calibrating split Lantus dose with Carb Free meals

A few months ago I split my 10 units of bedtime lantus dose to two doses settling to 5 at breakfast (between 8am and 9am) and 4 units at around 11pm with evening meal being between 7pm and 8:30pm and bedtime about 1am.

Found the split dose giving better results but there were still issues and my recent other change to count 1 to 10 as 1000, 2000, 3000 ... to 10,000 I think increased my Lantus dose because of the solostar continuous insulin leak after reaching zero (see other post). So decided to start at square one and work out my Lantus need with zero carb meals. Each adjustment to the background insulin takes 2 to 3 days to settle down so now I am in Day 5 of carb free food !! and it is looking all good except for last night woke up in the middle of the night and felt BG being low. It was 4.8.

Would be good to get extra pairs of eyes and some input from others as to what further adjustments I should do before going to normal meals and start re-calibrating my QA:CP ratios with the new optimum BI doses.

I am using half-units pen for the QA (Novopen 3 Demi for Novorapid) so the QA doses can be set more accurately and I have also shifted a bit from DAFNE ratios using fractions other than half-unit fractions for the ratios where I found it necessary. Looking at today and yesterday figures may be there is scope for increasing the morning Lantus - unfortunately there isn;t a half-unit solostar pen and would have to be a full unit.

Anyway - please have a browse at the diary and my figures and doses since starting the zero carbs meals on the 3rd of April

Thanks
