Prevention: verapamil, prednisolone, nerve block

Prevention reduces attacks during a cycle. Per the 2023 European guideline: - verapamil at least 240 mg a day (with ECG); - a short steroid course as a bridge for the first days; - greater occipital nerve block; - alternatives: lithium, topiramate, galcanezumab (episodic form only). Who has tried what? How fast did it work, what side effects, how did you find a doctor to prescribe it? Source: https://pubmed.ncbi.nlm.nih.gov/37515405/
