I rarely get sick. However yesterday i woke up at like 8am with blood 4.2 i did ussuall amount of novo for breakfast. a few hours later i got a bad headache at 11am and i did my blood it was 3.6 so i just corrected tested later and it was still 3.6 so corrected again and tested and it was 4.9 so i had my lunch then. I still had a headache and too the point i felt like i was going to throw up and like 1 hour later i did. But then at supper i was able to eat more my dinner and i felt fine today. So was the throwing up just my body not cooping with the sudden change in blood sugar or just a one off thing? as before when i have been sick i throw up for at least 2-3 days. Have any of you guys had a similar thing happen? and can Hypoglycemia make you vomit?
