Girl I have one right now too - actually I have had one every single day for the past 3 days and it is about to drive me insane. I am so SICK of having them all the time!
South Texas gets VERY hot (humid) and every year when summer rolls around I start getting these MASSIVE headaches. The only thing that helps mine (other than getting out of the heat) is to take Advil
I hate taking it all the time because I know that it is hard on your stomach, but it's the only thing that helps my headaches. And I talked to my father in law about it (he is a doctor) and he said that it's fine as long as I don't take them EVERY SINGLE DAY...which I don't. But I do take them when needed!
