I've had some real bad headaches every since I was 16 years old. I remember one time maybe 2 months after I had Kaitlynn. I was having bad headaches almost everyday. One day I thought I was going to black out. I don't know if it had to do with my eyes needing to be checked or not. They did seem alittle better after I got a new prescription. Sometimes I still get bad headaches. I don't know what causes them.
