Yeah my mom is a nurse so I steal hers because she has one of those expensive ones that you get from hospitals that is pumped based with digital interface. I feel perfectly fine, but if I don't eat after I workout I fee like I'm going down not sure on insulin issue or not.got it. Sometimes people just say they feel like its high without testing. Interesting.. I will have to keep an eye on it.. I don't have a tester though. I have no reason to think its high as I feel pretty level when on it.
