I hardly take any insulin in morning, have 1 sachet of porridge, if my blood is lower than 4.5 I won't take any insulin until I have a short break before going out on delivery, I like my blood to be around 10 when I start as we basically walk constantly for 3 1/2 - 4 hrs! My blood can be as low as 2.5 before I feel any effects in my feet usually 1st, I am not getting this everyday but it has become more regular lately without any real change in what I do in mornings. Because of my job I test around 5 times a day sometimes more if I have had low sugar, don't know if it's a confidence thing or what as never felt like this about it before!
