I get a bad migraine once a week and Imitrex usually gets rid of it. However 3 days a week I get a mild migraine and I just put up with it and take no medication. My doctor has suggested taking a glycinate magnesium pill each night to ward off the mild headaches. Since starting the magnesium pill it seems I have had a mild headache EVERY day! Could it be the pill? Do anyone have any experience with this problem?
