Yeah, my CH are episodic too. While I cannot imagine having to deal with the threat of one of these monsters on a daily basis as chronic patients do the blindside nature of the episodic form is no picnic. My tanks are the E size and I do recall my physician informing me insurance now covers this so I may need to find a way to add supplies to my 'durable medical equipment cave'.
I just ordered the mask from Clusterheadaches.com so this will help. I have most of the supplements listed above in the house but I'm also a celiac patient so I'll need to order the others from appropriate providers if necessary. Both the Bio Tech and LiveWise state they are gluten free. I suspect certification may not be needed.
I'm glad I registered today...this was overdue.
