I was just gonna post what Snoopy did. There are only 4 remedies under headaches at 5am (this doesn't guaruntee that one of those is yours but it is a great modality). I wouldn't follow the advise of your chiro - rather, see someone in person who is a classicaly trained homeopath, get under the care of Dr Leela online or even try posting your full case here.
Man, do not pride yourself on your superiority to animals. For they are without sin and you in your greatness defile the earth by your appearance on it and leave traces of you foulness after you. Dostoyevsky
