I have severe, chronic migraines. My neurologist says that on a scale of 1 to 10, I am a 12. Like you, I have vertiginous migraines. Due to the severity of my migraines I do not have much luck with medications. I did however, stumble upon an herbal remedy that I've had some success with. It's called a "migraine bomb." It is 6-8 drops of oregano oil and 6-8 drops of frankincense oil in a gelatin capsule (I buy the oils and capsules at Sprouts. You can also buy them online.) You can take it with water but I take it with milk. It helps with the "oregano burn/burps" that can happen. I hope you find some relief with this.
