Today I was driving home from work and still had some distance to go and started feeling funny like I was about to hypo. I was also yawning excessively and getting headachy. I had managed to check my sugar at 2 red lights (the first changed too quick) and was sitting on 5 exactly. I probably should've pulled over, but didn't have anywhere to pull over on that road. But going on how I was feeling I didn't figure that was safe to do nothing about as I drop super quick under 5. So I had a juice while driving. I get home 15 mins later and was sitting on 4.7, so had gone down .3. I figured in actual fact I would've been a lot less than that if I didn't have the juice (200ml). So I waited another 15 mins and finally it went up to 5.7. I figured I'd better eat before it drops again. But I'm so thankful my instinct to check was right as I could've easily hypo'd whilst driving. I'm glad I can pick up when my sugar is dropping quickly. My body starts warning me... it's definitely due to the quick drop though. Phew.
