Yes, I haven't read (or posted to) the tracking thread in months. But I do check the statistics on http://www.ccsvi-tracking.com
pretty well every day. For the last few months the overall results have held quite steady: over 2/3 of people treated are seeing marked improvements (especially in fatigue, but in other symptoms as well), while most of the remaining 1/3 are seeing no change. Before I was treated, I tried not to hope for more than no change, so the improvements I've seen have been a big bonus.
Now that we have so many treated (13,000?) I find the stats on the tracking site the best way to keep up. The timeline graphs seems to show that people are generally reporting stabilization of their improvements into 10 months (which is as far as that graph goes, to date), so that is also heartening.
