Ouch

My head has been killing me for the past two days and I never get headaches. Julia was suppose to come over but she asked me to come to her place instead so I thought that maybe some girl time and fresh air will help my head. I came over to her house and it was still hurting but not as bad, so we made tacos. When we decided to go out for a walk, and walked by a bar we go to often we decided to go in and take a drink each. It was fine at first but now I'm on my way home cause my head is just getting worse and worse. This is not normal. Does anyone have any idea what if can be? Or have any tips on how to cure headaches? I feel like I've tried everything!
