My BS is a little haywire now. I used to be fine pre Op, but I get peaks and troughs now. I use a meter that gives me percentages (apparently the correct range is 4.5% to 7% mmol) Mornings I am fine at 5.5% ish, but some days I peak at 12% a few hours after eating, then other days a few hours after eating I will get a huge trough of 2.5%. Having kept food diaries and BS diaries, there is no discernable pattern at the moment, other than I feel tired and warm before it comes on.
My Doctor is filling me full of holes and running tests, but nothing conclusive.

It is a little frustrating, as I want to apply for a job on the railways when I leave the army, but if I keep having these BS problems, I can forget any safety critical job.
Any ideas would be gratefully received.
