I have found a wonderful neurologist who did not give up on me. You need to find another one. I am on a combination of 4 different preventatives , plus Axert when I get a migraine. I also take Petadolex, Magnesium and CoQ10. I have an oxygen tank in my house to try when I get a "bad" migraine. Included in the 4 daily meds., I take Lexapro which actually helped with the migraines. I've had chronic migraines since I was 8 yrs old. I've tried countless things to try which did not work. Good Luck!
