Can't remember exactly what my blood sugar was at the time-- it may have been 1.2 mmol/l, but it was the scariest experience in retrospect, because I know that there's a few minutes during that time that I just can't remember. I'm not sure if I blacked out, but it was certainly possible. I remember trying to tap my boyfriend on the nose with a cereal bar wrapper, and being totally fixated on doing this. Then I woke up in torrential sweat, with a big bright yellowish light in front of my vision. When I was trying to get my glucose, moving over in the bed, it felt like every nerve in my body was shattering. I'm not sure if I passed out, but I feel like there's a couple of minutes I'm missing from my memory. I was lying down in bed, it could have happened for all I know.
It's moments like these that teach you lessons about your diabetes. Scary stuff.
