We have had to administer the glucagon shot to our daughter, Lydia, 5 times since her diagnosis 16 months ago. Each time she was in a full grand mal seizure and it took about 10 - 15 minutes for the shot to pull her out. She never threw up but, she did complain that she had a terrible headache and her stomach felt ill afterwards. Fortunately, I work at the school she attends so I was there the day she passed out and seized in class. I have never been so scared in my life. I sympathize with the rest of you that continually check on you children! Sometimes I wonder how I actually get any sleep when I realize how often I checked on the kids at night!
