Siddy, 42 is a VERY low blood sugar and is usually treated with orange juice with a little sugar in it. I am a pre-op and don't know for sure what you can use, but you HAVE to get it a little higher. Not trying to scare you, but if it gets much lower, you will pass out. It can also get too high. Diabetes management is a tricky thing and needs to be monitored closely. I am sure you can find more info on line or from other AMOS ites. I am not diabetic,(YET) but it is rampant in my family. Please talk to your Dr. Elizabeth
