Hello, fellow migraine sufferer here. The continuous HRT definitely reduced the severity of my attacks and after about 6 months the dreaded vomiting stopped. I've been on continuous Utro and Sandrena for 16 months. It is definitely worth trying as you say level hormones are better for us. I was nearly 55 when I started HRT and had nearly 1 year period free so went on continuous HRT. I have not seen anything relating to a cut-off age. I think that as you are post-menopausal for a number of years it would make good sense for you to try it. I love having no periods, my migraines were off the scale when I did.
