I'm trying PCA by Maxam, it binds the toxins & removes them so you don't get such a healing crisis. I hear that bioray NDF is good as well, but haven't tried it. I have been taking the PCA for 6days & no bad side affects yet...It is too soon to say, but I think it is working & I am starting to feel better not worse. It is a sublingual spray & has very little taste to it. It seems too good to be true, so I am going to try it for 30 days & then report back to curezone on my results. I have read some good reveiws & the only skeptics seem to be those who have not tried it because of the cost. I got the trial size of 2 bottles for $35, a small price to pay for relief if it works.
