@benchi300 I can't edit my post from yesterday, but I made a mistake about Emgality--it was prescribed for MIGRAINE prevention and is good at that! However it did not impact my nocturnal headaches. I take Ajovy now for prevention of Migraines. Emgality (for me) was more effective than Ajovy at preventing headaches and for improving my color vision, visual acuity, and reducing my blinding persisting "afterimages." Both skin health and hair health improved dramatically after several months on Emgality. And Egality reduced severity of prodromal early symptoms (nerve/muscle twitches, scotoma, numbness).
