Right, but my CWD is one of those who needs to eat a mix of carbs and protein after the fast acting carbs bring her up, in order to stay in range. The longer we try to treat with JUST fast acting carbs, the deeper the lows and the faster the drops. I have no idea why, I just know it is a consistent pattern. YDMV, I guess! Usually it is not a problem...I just keep snacks in the car and get them if we need them. But at amusement parks I like to keep everything we need WITH us and the snacks typically get crumbled/crushed beyond anything edible. And we struggle with blood sugar levels at amusement parks, anyway. She typically runs low, but if we cut back on her insulin at all, then she runs REALLY high and has to go potty roughly every 45 minutes--no joke. I have no idea what a Disney trip with multiple days in a row in amusement parks will be like...but I refuse to let D keep us from our "normal" life, so we will find out! We will just do a lot of playing by ear. You never know...maybe multiple days are what we need to figure out how to overcome some of these issues! ETA: At meal times in particular, this would be complicated by the fact that she goes low if her meals are late. I know this should be a sign that the Lantus is too high, but if we decrease it, she runs high through the night. I dunno. We'll just see what happens and treat and move on!
