Ok since I'm 26 weeks pregnant I can't take my migraine meds. Anyone get the ones with halos. Sometimes I don't have pain just the halo blindness. I was just wondering if there were any natural things I can take to ward them off. My trigger is stress. So getting rid of that is impossible. I'm having one now so hope my spell check is working. The blindness lasts from 20 minutes to an hour. Any helpful advice is appreciated
