here goes. I went to a new neurologist yesterday he increased my Verapamil to 600 mg. Is sumatriptan I take as a nasal spray and it's 20 mg. He gave me an order for oxygen, my insurance won't pay for it I can't afford to get it. And I just found out today that my insurance has cut me back on the sumatriptan from three boxes every 21 days, two boxes every 30 days. I don't get many breaks from the Clusters. My last bout what's 2 weeks straight up to for headaches a day. Then I have 2 days off and started getting them again last night one last night and one late morning which is unusual. I usually get them from late afternoon tonight time. Something has got to work I can't handle these headaches.
