How long had you been ill before you found out you had candida and parasites?, do you feel better now than you did then? two years is a long time to be cleansing but I guess it takes a long time to get ill in the first place so healing isnt going to be quick.
I think I have had parasites from a very early age but things got quite bad about 2 years ago when I had to leave work because of ill-health, I worked in a soil testing lab !! couldnt have picked a worst place for parasites!. Have to be thankful that it lead to my discovery of them though.
I used a product called ThreeLac to reduce my candida which was really effective, I sell it in the UK but its all over the net.
