You are welcome. If you feel a bit off, go back to the norm. If fine, start over. It has propensities to be a tumultuous, taxing process.
In a cruel twist of fate, and this is how I know that I am not smart, the medicine won't help while you take it, but coming off-be prepared for the worst headaches of your life, and I don't know why. Someone a lot smarter than I am will have to explain how that works. You will most likely get some nasty headaches that will have you screaming bloody murder.
Second, I added in the Benzo use because that class of drug, in conjunction with the antiepileptic (anti-seizure), is super nasty to come off of. Certain psych meds as well, but the aforementioned can have you come close to needing a chemical straight jacket, i.e. a potent neuroleptic.
I know everyone knows what CSD is, neuroanatomy 101. I thought that the following articles on Cortical Depression Spreading were necessary, and if you pay attention to the Ca+ waves, it makes sense why Toprimate is efficacious in Migraine, why it can prevent or reverse chronicity. Toprimate targets the Calcium Channels, but not like a blocker say Verapamil. I know, everyone knows this: I will post for those that don't.

How does this help you? Well, unfortunately, about everything starts with Migraines, and CH--the redheaded stepchild--follows suit. I will have to look at the latest neuroimaging journals and see what is in the pipeline for CH. There is far more than people realize.
Oh, and yes, these are old journals, but sometimes they are reliable. People make the mistake of thinking that the latest, is the greatest. And then, they fail to realize that so much of what is available today is questionable, ghostwritten, sponsored by someone such as Lilly or Pfizer, good luck discerning fact from fiction.
