I wanted to follow up with everyone on my post on August 25. The week of the 25th we were away on vacation and the attacks gradually got a bit stronger. When we returned home I had another Emgality in the fridge as the pharmacy had given me two injectors when I refilled previously which is why I think the neurologist gave the pharmacy a migraine script so that I could get more. How and ever I had now taken 4 120mg injections in a little over 4 weeks which is about right for an episodic cluster patient. Regrettably the attacks have returned to their full intensity and after a few really bad nighttime attacks I have started the prednisone taper again which seems to be working. I think my next step is the alternative treatments. I did purchase the excellent book by Ashley Hattle and will use that as a reference. I suppose I will keep doing the Emgality as I can get it as I think it helps a little . I do have a request to the community. I need to find somewhere in Northern New Jersey area, Rutherford , Hackensack Nutley area to get an oxygen tank etc if anybody knows. Thanks
