| A few things Jodie.
I find it hard to believe this is your first such hypo in thirteen years. By my thirteenth, I was a hypo pro. I nodded off all the time and I still do. I'm up to 10 such incidents in 2007, my lowest ever. Either you've had great control or you've always run high. I would bet a lot of money that your basals are pretty flat. I highly suspect your future experiences with hypos will be very good.
I take any need to correct as a sign of trouble. Too many times it's been a high GI sugar spike that didn't need to be treated or just laggy insulin that decides to kick in later. I now always set my alarm(s) to get me up through the nights.
You are lucky to be 18 and be at the height of hypo-awareness. The bad news is this will all but disappear. I got 911'd for the firt time at 34. I grew up feeling I had everything under control because I could recognise all my hypos and hypers. That was before the internet. I learned the 'old fashioned' way.
You were really not in any danger. Your liver most likely would have saved you. Did you go high later? Mine has brought me out of every hypo I've ever slept or convulsed through except for one. On that occaision I took my morning bolus and fell asleep on a chair. Ow! The real danger is the things you do while hypo such as driving, tree climbing, and wood working. Always test before such things regardless of how you feel. |
