I used to get headaches too. I finally figured out it was three things that would get me. Being dehydrated, exposure to perfumes, colognes and other scented household stuff like cleaner solutions, and the 3rd was industrial and household solvents like lacquer thinner and acetone (fingernail polish remover).

It took me years to figure that out. Perfumes and scents are so pervasive they're easy to ignore as a trigger for headaches but they get to me fast and the headaches last a long time.

I avoid that stuff like poison now. I will leave the area if I detect it.

Getting outside and breathing fresh air always cured the headaches from perfumes and solvents. It was the only thing that did get rid of them. Over the counter meds did nothing for me.

I use an activated charcoal filter on my tap water now and that makes drinking water a pleasure again. And I pay closer attention to not letting myself get dehydrated. It's easy to tell, I just press a fingertip and if it leaves a dent I need water even if I don't "feel" thirsty.

So, if these are what's causing your headaches you need to be proactive to prevent them and to get rid of them, and a "fitbit" won't help much with figuring out the cause.
