Suggest Treatment For Migraine

I seem to be constantly dealing with some level of migraine most days. I know that some are triggered by hormones, weather, certain foods/additives, chemicals in the environment such as perfumes/fragrances, etc. i.e., not stress or tension in my lower neck/upper back. They are primarily in the front/top/sides of my forehead and usually more on one side but then radiate into my cheekbones, jaw and toward the top and back of my head. I am very sensitive to EMF s and am now wondering if they just might be the main cause and what to do about it other than live off the grid. I just saw on this site that someone was recommended a mineral called Tektite? I do take magnesium 200 mg in my morning multivitamin and another 400 mg at bedtime to help me sleep. I can t take more because I have Ulcerative Colitis and more will cause diarrhea. I also have Fibromyalgia-Chronic Fatigue and suspected Lupus. In spite of having dealt with these conditions my entire life, yes, in childhood as well, and I am 62 now on BHRT, which is the only thing that seems to have helped, I am happy and practice meditation etc. to deal with lack of sleep, pain, fatigue and depression. Would you recommend Tektite? If so, what dosage? I am currently taking Sumatriptan 50mg tab for my migraines only when I absolutely need to as all meds seems to have undesirable side effects. However, I am not taking any other medications at this time. Thank you for your consideration:)
