Your experience at the second colonics therapy clinic sounds terrible. Kind of like the same treatment you'd get @ a nursing home...no respect! Good thing you stopped going there.
I just wanted to mention that I used to get chronic yeast infections, at least every 2 months. I took acidophilus supplements and ate yogurt but I still had to buy the treatments at the pharmacy and they would go away in a week.
I did a parasite/colon cleanse last fall and I have not had a yeast infection since. I don't eat dairy and haven't been taking any probiotics either so I give credit to the parasite cleanse I did by taking capsules of mixed herbs that help expell parasites.
Just a friendly suggestion to help you with your ills :)
