Yes the rage low is not the best but I suffer from an even worse low blood sugar symptom. I often yawn when my blood sugar is low, a low being between 60-80. The yawn low has shown up at the worse possible moments, from the last seconds of a very close game that I was coaching to sitting down with the boss to discuss a problem on the golf course. It is a very clear sign of a low blood sugar, I shouldn't be yawning at 2pm while trying to learn something that truly interests me at work. The people that I see everyday know about the yawning low but it is the people I don't know that take the yawn to mean something else. In fact I have had parents ask athletes why their coach was yawning as the team came out of a timeout in a game that we were trailing in the final seconds. Explaining that was fun and of course the parent felt bad which made it a very awkward situation.
Of course it would be great if each and every diabetic had the same symptom for every low but where would the fun be in that. The yawn pops up at bad times but it is amusing when it appears around good friends. This sounds weird but I like when a buddy asks "Do you need a nap?" at 9am as I'm preparing to go for a bike ride.
