In Aug. 2003 (after 4 years of no CH) I was on verapamil, lithium and later the neuro added Topamax - I could barely think at 100 mg. but was advised hang in you'll adjust and I did. Gradually up to 400 mg., 300 lithium and 480 verap. And yes, I worked and actually could think...but I still had bouts of CH so it wasn't really a great preventative cocktail after all! I always used 02 also at 12-15 lpm for 10 -12 min.  I was chronic from 2003 to 2009 summer and then ended! Until this August. DANG! I had tapered off the above in Dec. 2009 and except for 2 or 3 brief times, was PF until Aug. Tried RC seeds once and got more hits than before I took them; was going on vacation so back to verap. at 180 for 5 days, then doubled it; a 6-day course of prednisone too. I was desperate to enjoy a vacation! I had a lot of CH on the trip - no fun with no 02 available (Alaska fishing the rivers on a small island). I hate to think of going back on conventionals so hope to taper off again and try RC again though it seemed I sure had some hits afterwards - unless a cycle had just started. I was hoping for a 4-year reprieve again!
