I went straight for the Synergy (Single Stage) primarily to save some $$ while hopefully still healing myself. I have no prior experience w/ozone equipment at all. The O2 concentrator I have is a supposedly "refurbished" Airsep New Life. The beeper doesn't sound when you turn it on but is most definetely pumping oxygen out.
I'm sure it is working at some level but just based on other people's accounts of how strong O3 - Ozone is I seem to be having negligable reactions so far.
It's weird. Part of me thinks this might mean that I am on the verge of overcoming my illness while another part of me thinks I am so sick that I am responding to no treatment whatsoever.
Perhaps I have permenant brain damage and this is as good as it gets. That would be the worst case scenario but it is possible.
