The writers used some poetic license with the daugther's diabetic situation, but I'll give them a pass. Still, it really annoys me when misinformation is given on diabetes. This is based on my experience, research and doctor's advice for many years.
They made it appear that Lacey was sweating. Sweating is a sign of HYPOgyclemia, not HYPERglyclemia, as they said. HYPO is low blood sugar and it would mean you had too much insulin and your sugar level was low. You would need some juice to get it up. You would also feel faint and have symptoms similar to Lacey's. HOWEVER, Lacy's condition of having NOT enough insulin would simply mean her blood sugar was too high. Normally, you have to have very high levels for a long time to get really sick. Just running out of insulin for a few hours, would not cause this unless you would consuming huge amount of sugar. You would have dry mouth, nausea, stomach pain, and eventually difficulty breathing. This normally takes days to get. It's almost like they reversed the symptoms with Lacey's condition.
I'm a Type I diabetic and I have suffered with Hypothglycemia so bad that was hospitalized for it. Sorry for the details.
I hadn't thought about why shows are not faring well upon their return, but I agree that these long breaks are not a good thing. I'm not sure what the answer is, but I wish they would go back to where there are new episodes throughout the year and then a break for the summer. What happened to that? Now it's like new shows for a couple of months and then nothing for a year. IT's crazy.
