Quote from MarilynWeakley:

Those attacks of lightheadness could also be realted to anemia. How is your iron intake? I would start taking some multivitamins. (this could help many problems) If you have problems with your stomach there are adult chewable types and liquid types such as Centrum. Let us know what you find out at the doctors ok?!
Also, could you be pregnant?

I'm a guy. And for the other question I'm not sure if my iron level is low or not. I did have some multivitamins I was taking, Kirkland brand, but I stopped taking them ever since I started taking doxycycline and benzoyl peroxide for acne...it would probably be a good idea to start taking them again though...
