Well, welcome to the club. Talking about poo is pretty common here, so no worries. Quite the contrary it is smart to keep having a look in order to know how good you are doing.
What you describe up there could pretty well be candida or most likely simply parasites.
Candida and yeast are white, and stringy. DO visit the Images gallery for pix of candida.
This will be better than any descriiption I could give.
I would strongly suggest you take a look at the parasite forum as well. Some parasites are white as well and it gets to be pretty confusing. Here are some pix:
If you were positive it is candida (constipation? brain fog? floaters in your sight?) I would tell you to go straight ahead with Humaworm and the diet.
Yet, acne and hives are sign that your bowels are suffering, which might indeed be candida or else, just parasites, in which case, Humaworm (all natural herbs to kill both parasites and fungus) or another parasite cleanse would do the trick, without following the diet.
