Why am i getting headache if i can't drink coffee?

Well you can drink other things that have caffeine in it. A caffeine headache just means you need something that has caffeine in it doesn't mean you need to drink coffee. So you can have a soda or even chocolate which ha caffeine in them both. When I was pregnant I would get them a lot so I would work my way down from my normal amount of soda and put in it's place chocolate here and there and over time I would stop having caffeine headaches over a few short weeks.

There is a valid reason for that.Headache is caused due to swelling of a perticular blood vessel in head suppling blood.Coffee contain a potent constituent that is caffeine and it causes constriction of blood vessel.Just after taking coffee the dilated blood vesssel in head come to normal and helps to get rid of headach but its effect on other blood vessel is quite controversial and yet to find out.Sometimes headache may be a withdrawal effect of caffeine who are addicted to this.

They are right. Maybe you have what we call "caffeine withdrawal syndrome". If you want to slow down drinking coffee to fix the problem, my suggestion is, don't stop drinking coffee abruptly. Do it gradually by shifting to coffee brands with lower caffeine content. There are coffee brands which contain as low as 0.06% content only, and still taste good.

Just in my honest opinion, I think you have caffeine addiction, now when caffeine blood levels go down, then you experience these symptoms, it's similar to addicts's withdrawal symptoms, you have to bear with it for a while, try flushing it out with plenty of drinking water, seems like the body is craving for coffee rather than feeling thirst, again i have no medical basis but this is what i think based on what little i know

That's what happens in caffeine withdrawal. If you say you like to drink it every few hours then maybe try limiting yourself at first to a few times a day to then maybe only once a day. I used to drink soda a lot and I'm trying to only have it every once in a while. But at first, I'd get a headache if I went a day without soda. It would be a very bad migraine that only a soda and a nap could fix. I still drink soda but now I try to have it at least once every two days, if not longer.

You have a routine, and are addicted to teh caffeine and what is inside it. You will get a few headaches until your body gets over that withdrawl or you have coffee. I remember working at a coffee shop I got into a routine of drinking coffee over the shift, one night I thought about it, and thought I dont want to spend all that time and money on coffee, so I went about a week and a half with big headaches before I was fine.
