Since either overhydration (drinking too much water) or dehydration (inadequate water replacement) may along with other factors precipitate a migraine headache, the answer to your question is to change your water drinking habits one way or another over a period of time and observe and record the results. In any event, since you haven't described your full medical history, the above suggestion should be done with the approval of your doctor. ..Maurice.
