Sometimes, if you can narrow down the cause of the headaches, you can avoid them. If I'm stressed I tend to clench my teeth which will trigger a right sided headache. I got a little appliance from the dentist to prevent the clenching and thus the headache.

If I don't drink enough during the day, I'll get a top of the head headache from dehydration. Water solves that one.

Taking certain drugs, like Tylenol, can cause rebound headaches. I take Aspirin (well, generic ASA, actually) and it usually does the trick for me.

I hope you find a solution - headaches are miserable.
