One of the ways that I do when I have a headache is to drink lots of water. As we know that water is very good for health. Even doctors recommend drinking eight glasses of water a day. and apparently what I did when I had a headache was by drinking two glasses of water. really feels the benefits. For those who want to practice please. This is not scientific research, this is actually pure experience of how I deal with headaches without drugs. Thank you so much
