Thank you for your prompt response. I am working with a Diabetic Nurse to get my blood sugar under better control, keeping food logs with insulin-to-carb ratios, and really keeping BGL down during the day. Now we're working on minimizing all the lows I've been having during the night. Maybe it's just a temporary adjustment problem. The bright spot only happens during hypoglycemia and is not like the visual aura (bright shimmery zigzaggy spiral and blind spot that grow and then fade away) that happens with my occular and classical migraines. Thanks again for your comments and recommendations.
