I keep sports gel in my messenger bag and in my car. I also have several co-workers from different departments keeping a gel-pac for emergencies. They only cost about $.79 to $.99 each. The down side is that they are 21-25 carbs apice but most of the time I need more than 15 carbs to make the hypo disappear. They are sold at any sporting goods store or at all Academy’s.
I’ve done the sugar water trick a few times too. But the worst for me was when I was at Camp Njeda in 1982. The counselors all carried tubes of Karo corn syrup with them when we were out in the woods or on the lake. That was the beginning of my aversion to high fructose corn syrup. Nasty.
