Hi Dean.  Yes, I was taking extra HCL for the past year.  I made up a 5% 
solution of HCL (food grade like Dr Clark recommends) and took 10 drops 3 
times per day.  Didn't help.
I sort of think that I had too much HCL caused by acid reflux in my esophagus 
and that countered any Cs from helping out.  I was making a very weak form of 
Cs and plan to do like James suggested to cook it longer also.  I also was 
switching from 30 VDC to 15 VDC the last 15 minutes.  I now am staying with 
30 VDC.
