great info @CHfather. I had the opportunity to meet with Dr.Goadsby a couple years ago, 10 months into a severe episode. I found him to be extremely empathetic to CH, but about as helpful as my other neurologist. He kept me on a 10 day steroid taper x1 month, and told me to take less imitrex. when I asked him about mushrooms, his response was, "what like those clusterbusters". He definitely was not a fan and probably why I have waited so long to try alternative treatments. I swear that half the battle of CH is managing my doctors. I wonder how many others on this site have also seen the same doctors, getting the same results.
