I currently take 2 Sandomigran (Pizotifen) tabs each morning along with two glasses of warm water.  I started with one and did have a bad headache and teh doctor advised that I then take two. I now find it so good to be relieved from my headaches which I used to get so often atleast 2 to 3 days a week. However I have also, on the doctor's advice, stopped my daily coffee. I used to have just one cup a day. So I suggest that if you are a coffee drinker stop your coffee for a month and see how you go. also drink  lots of water at least 8 glasses a day. You will surely find an improvemnet. Also ensure you have at least 7 hrs sleep. I used to have late nights (movies) and go to bed at 12am getting up at 7am. I have since changed my sleep pattern and have found my headaches gone. Hope you get better and Godbless.
