I had one, but so far I’ve been lucky to pull myself out of deep lows. I don’t have them a lot… mostly small stuff that I combat with crackers, juice and a little slow-down with a dab of peanut butter. So my emergency kit expired.
However, my friends and family are horrified to use it and want no part of it. So if I ever go unconscious, I’ll be waiting on the paramedics… I don’t know… if it ever really happened, you never know how people will respond, but training them on it only freak everyone out.
