New here; type II from outside the UK (but travel there with some regularity, if that counts). In regard to the original post, even my doctor told me to read the Glucose Goddess material, which I did. I read it critically and highlighted as I read (my habit); some was common sense, some I disagreed. I think it's more appropriate for non-diabetics. I do like the Jenny Ruhl books, though I disagree on some points there, too.
I travel extensively, frequently across the dateline, regular trips to Africa, Europe, the middle East, Australia, south America and Asia as the south pacific. The time zone changes, generally on a daily basis, mess with medication, circadian rhythm, and meals, and introduce problems with glucose control. My diet is often limited to what's on a flight, and the hours I arrive and leave at locations make choosing food, or obtaining food, difficult or impossible. I'm often left to eat whatever I can carry, which is typically limited to small packets of nuts or nut bars.
That, in turn, can lead to frequent discussions about diet (sorry, I can't eat that...). The public perception that one makes one's self a diabetic through abuse of sugar is the most common misconception that I hear. In fairness, I did carry a bag of red bulls in my travels and was as big a sugar abuser as there ever was, until discovery of diabetes; timed close to the discovery of my father's demise due to diabetic keto acidosis (I wasn't aware of his diabetes; we didn't talk much, or live nearby). Radical changes since. Public perception, and functioning with a crowd out to dinner or on a flight does prove, at times, a bit troublesome, and frequently leads to only eating small portions of what's available, to avoid carbs, etc.
