I have suffered from CH for 20 yrs. with breaks of 5 yrs in between the Kip 9 + that lasted 2 months. Recently hit again 3 months ago. Oxygen has been a fantastic abortive. Steroids effective but only briefly. Varapamil ineffective. Recently the D3 regimen has been introduced and calmed the beast in a few days. I plan to continue this therapy throughout my life, and of course monitor the levels with blood tests. In retrospect of my other cycles, I can't help but realize that I was rarely PF. The shadows were always lurking but I learned to live with them. Back then I was not aware that they could hang around and was elated knowing that the excrutiating pain was at bay. I am confident that the D3 regimen will keep the beast at bay. There seems to be little to nothing else available as a prevntitive that offers other benificial results. Can anyone recall thinking the beast was gone, only to learn more and realize it was lurking ? low pain, occassional sharp hits lasting seconds etc ?

Thanks Barb. happpy to hear of your PF anniversary.
