I know that the occasional lightheadedness and dizziness is normal. But ive felt slightly lightheaded for about 2 weeks now. Today I had one of our nurses (Im an STNA/receptionist) check my sugar. It was 79. He had to stick 3 different fingers before he could get one to bleed at all. I had eaten a snickers about an Hr before that and Ive been drinking juice all morning. Now Im kinda worried...Any input?
