I am glad this does not contain sugar.
However, It is important to remember our diabetes is affected by more than just what we eat and things like pain or illness can cause a liver dump which can raise BG. Therefore, it is important to weigh up everything. For example, if you are taking paracetamol to ease some pain, is the pain affecting your BG more than the contents of the medication?
It's good to know you do not have to make this decision this time - something to consider for the future with, for example, cold relief drinks.
