I'm going to talk to my endo about this when I see her this month, but I'm wondering if some insulin users are just always dizzy... Because I am. Ever since I started insulin treatment three months ago, I've been prone to dizziness no matter what my BG is. I mentioned it to me CDE near the beginning and she didn't think it was insulin related, plus I was already having symptoms that I knew were stress symptoms for me... so she and I chalked it up to stress. Then is lessened to where I barely noticed for little while, but now it's more notable again.
I honestly do have a lot of stress going on in my life right now. I hate my job with a passion, my boss stresses me out (sometimes intentionally, if she thinks I'm not upset enough about something that went wrong!), I'm job hunting (with no promising prospects), we've bought a new house and are still unpacking, we've been planning for a baby (which this diagnosis has put on hold for a while), and--OH YEAH--I was diagnosed with diabetes three months ago and am still adjusting. So stress still might be the issue... but it's a pretty big issue, because it makes detecting hypoglycemia a lot harder. :(
