I was recently told I had diabetes,but no medication or treatment was prescribed. Since my Mom is diabetic, I knew at least that low sugar could cause coma,etc. so I bought the Reli-on at the Sam's pharmacist's recommendation. Driving home from work one day I felt shaky, headache, blurred vision.Having had a low sugar episode several years earlier,I suspected that might be the problem. I pulled into a gas station,my hands were trembling so badly, I could barely pull the test kit from my purse and unzip it. I actually started to put the strip in upside down. Not even pulling the monitor from the plastic sleeve,I managed to poke my finger. By then my hands were blue and it was hard to squeeze out even enough blood for the test. The results came back very quickly--40. I staggered into the 7-11 and grabbed an orange juice and sandwich, sat in the car for about ten minutes, by then my sugar level was up to 60 and I was able to continue the drive home. I really appreciate the compact size, ease of use, all the little pockets for the test strips,needles,alcohol wipes, and other equipment. It has become my second "VISA"--don't leave home without it. I also now carry a small vial of glucose tablets in case no fast food places are nearby or open.
