I think if you do the full four cleanses (and do me a favor....do them in the recommended order! ;-) ), you'll be amazed at what your body can do to rid itself of "things". Also, since you mentioned it looks as if it may be yeast related, I would suggest the CoQ10 treatment after a couple of weeks on the parasite Cleanse. I would continue with the regular use of a sterile eye wash too, just to help with any flushing action.
Keep us posted, and good luck......you'll be SO glad you did!!
