Hi Snooze, even a jump from 7.5 to 22.5 is large.
I just wonder whether although you maybe getting a large spike that some of it is a rogue reading maybe.
Maybe need to make sure very clean hands before testing or at least retest just to make sure. If you have a reading that high on 2 hours I would be testing again say 2 1/2 then 3hr to make sure it's dropping at that point.
Knowing what you figures where (HbA1c) will give you an idea where you started, co's if you started high then it may take a little time to come down over a period of time.
You mentioned the weight coming off, if you are overweight then this will contribute to those high figures. You will become more sensitive to the insulin as you lose the weight which will help to keep your numbers down.
Your really do not want to be in those ranges so eating to your meter will be the way to get them under control
You are allowed to ask for a print out of those numbers for your Cholesterol, HbA1c, kidney & Liver test, as usually these are the tests that are completed for the diagnosis. You could probably, like I did, just get them from your doctors reception you don't have to ask the nurse or Doctor.
I know the feeling having to have eggs and bacon, but you can have Omelette, scrambled eggs, with smoked salmon nice (very posh) Ham & eggs, Large meaty mushrooms. poached eggs all sorts of cold meats. I have yogurt (full fat Tesco's) berries, sprinkling of Granola, and some Flaxseed. when not having the bacon. I can manage 1 slice of Hovis Seed Sensations which sometimes have egg any which way.
