BIllyJoe, I only use it when I can not get to another source, I consider them Emergency use only. So Far I have only had to use the glucose "Tablets" 4 times in 6 years. And only had 2 episodes that I can remember where we were in walmart. I drank a regular coke, which got me sugar up to where I was feeling "Normal" again then we got something to eat. My Episodes are NOT severe, When I feel it starting to come on even the slightest I look for something to take, either food or the tablets. But I for one thank you for the information and I am sure other Diabetics here will find it interesting as well.
