I don't remember where I saw it, but some guy posted graphs of his blood sugars from his CGM during just a 1-hour stressful phone call, and it was an insane spike.
I've had sugar highs prior to long, stressful job interviews prompting me to take insulin which then brought me low, mid-interview. I then tanked the technical test. Thankfully the interviewers gave me another chance with a take-home test when they saw me pass out in the test room and have to give me sugar pills. You can't win, really.
And they say type 1 diabetes is a "controlled" disease, yeah right, maybe if you live in the mountains with zero stress and only eat leaves and do basically nothing all day, every day. Try being calm and composed to give an impression of confidence during an interview, when your blood is on fire and your blood pressure is through the roof, and tell me not to take insulin, which then, of course, works overtime and kicks you when you're down.
This disease sucks, even if you do everything "right". This is why I get angry when I see people complain about having poor health outcomes for things they can easily avoid. Even in the best circumstances and most monk-like discipline, this disease will make a mockery of your feeble attempts, so why exacerbate things and adopt a reckless "eating anything you want, any time you want to, and just take more insulin to cover it" approach? I find that mentality wanton and irresponsible. Frankly I'm disappointed by this forum, how common I see such laissez-faire, wishy washy anything goes mentality, coming from supposedly knowledgeable "experts" who frankly should know better and should in no way be giving advice for poorly controlled diabetics to use as rationalizations for not getting their act together.
