That's a lot of calories in one drink, dear god.  A couple of years ago my Type 2 diabetic boss wanted to get everyone oreo shakes from the Johnny Rockets around the corner... he wouldn't take no for an answer (if everyone had them, he had an excuse to hurt himself with one).  I figured whatever, I'll drink a little ice cream and toss the rest, but I have a Type 1 diabetic coworker that actually does take care of himself. I asked him if he wanted me to check the sugar and carbs online, he said "oh no, thanks, don't worry, I'll just estimate and give myself a bigger shot of insulin this time to compensate."  I checked anyway... 1100 calories (Oreo Malted Shake the site I checked back then said to add 100 for malt shakes), Total carbs 114g, sugar 96g. I told him and he said "how much?? no way! I'd have to give myself more insulin than I take all day... I'll have a little now cause I already gave myself a shot, but just a few sips and then I'll throw it away" (which he did), my Type 2 boss did not share his sense of self-preservation.
