Like "There have been times when I have thought I would get up and be slightly dizzy and feel slightly faint. My bs would be in the appropriate range. I do, however, have other medical conditions that may cause me to be lightheaded or dizzy at times, such as high blood pressure, and a couple of other things. It is a good idea to talk with your dr. because the cause maybe something completely different than your diabeties. I'm not sure I've been much help here, but I thought I would pass on my experience. Good luck."
