L.S.
I had a problem for months with lightheadedness. It was finally diagnosed as panic attacks or anxiety disease. I was given a very low dose of Xanax(.0125 mg). I started off taking it three times a day. I felt great. After two months I decreased it to two a day and after a month I went down to one a day. Then I stopped it completely. Now I take it only when I get lightheaded. It happens mostle when I'm very tense or stressed out. I probably take one tablet 10-12 times a year. Good luck.
