This has been happening to me much more often over the past couple of years. I think in my case it might be migraine-related. I've been cutting down on the dosage of the daily meds I take to manage migraines during that time, and when I stopped taking them completely a couple of months ago, the lightheadedness got much worse. I went back on a low dose of the drugs and that helped.
