Thanks Tracey,
My DNS is now back, and she told me to do 36 units both morning & evening. Mornings have started going up again to 9 - 10 and before meals are still between 13 and 15. At the moment I now speak to the DNS twice a week and she is "upping" the units twice a week. The DNS did mention maybe trying a 50/50 mix as my post prandial are high as well, but will have to wait and see.
I am checking BS 6 times a day at the moment ouch!! :roll:
