I've been trying to figure out what exactly caused that. At the time I was drinking a lot of home-made lemonade with newly bought KAL brand Stevia as a sweetener. So 2 things could have happened:
1. KAL brand Stevia might have been cut with something that fed Candida to the point it formed biofilms, or
2. Acid from drinking lots of lemonade caused a hostile acidic environment, causing Candida to form a biofilm.
Not sure which of these occurred. I haven't tried them separately. I'm afraid of Stevia now.
Generally a biofilm is formed from my readings in adverse environments. You can find more info on it online. I don't have a microscope. I was thinking of putting it in a cup with sugary water though to see if it grows but I understand it needs to be a certain temperature. I'm looking for some labs now so I can test. I am especially interested in a lab with DNA strain identification. In my state I have found Texas Children's Hospital does DNA strain identification on mycoses. I am trying to figure out how to get them to take a look at a sample.
I don't think there is a big correlation with mood.
