Gave 2 units of 70/30 novalog pen yesterday morning, then ate an entire bagel with p. butter and small ch. milk at work at 7am. BG was 134 prior to shot and food. This is not my normal routine, as I usually eat at 5:30 at home before heading off to work. So at 8:15 it was 145, then came the blast! I felt terrible, 8:45 checked and it was 77, had a small sprite, checked and it was 72, had more sprite, checked it was 69, had some gatorade, checked it was 98, 5 minutes later 80. I must have checked my Bg's 15 times in an hour, as I felt terrible. Thought I was gonna pass out. With that said, is it possible to hit a muscle or vessel and it hits you like this? Normally I feel low at 70 or 80 but not that bad. This was scary. Then all day I had upset stomach and felt horrible, and still recovering today. Was diagnosed 2 months ago and my Bg's haven't been over 160 since on insulin. After this episode it all caught up and it went to 220 at 10:15. I'm looking forward to pumping as I feel like sometimes I have to feed the insulin.
