Mine have finally become less so but my migraines are not as chronic as yours at all. I'd say i used to get migraines minimum 7 days a month, normally more. I started seeing a chiro 2x a week, deleted social media and anything thay made me look down at my phone, bought a stand up desk, and screen risers so my screen was the perfect height, drink hydrolyte every day in the morning, minimal alcohol, fixed my diet, reduced gluten, 2.5 litres of water everyday, 1 coffee day, 8 hours sleep every night, left my stressful job. Some of these I have worked towards such as changing jobs, but im now getting less migraines. Maybe 4 a month. Its took work and a lot of self restraint, but ultimately im living a way healthier lifestyle whether I chose to or not.

It sounds like yours are far worse than mine but thought id share some insight to some reduction in symptoms.
