I heard about and got this medication for the first time last night in the ER and got relief almost instantly. I woke this morning at 4am with another headache and went to the walk-in clinic and asked for the same thing. Again, almost instant relief. I asked the doctor for a prescription, so he wrote me one, but in a city with 60,000 people, there are NO pharmacies that carry it or can even get it from their retailer. What now???
