Ok. If the symptoms are that close to your die off symptoms, then that is what it could be. If you want to continue them, I would recommend keeping at the lowest doseage and see how it goes. If you have signs of a true leaky gut, like your urine sometimes smells like what you ate, then do not take them. I’ve read a few horror stories of people taking probiotics with a leaky gut, one lady even had to have surgery done in her eye. Its not something to play around with. Some manufactures will even warn against that, especially with acidophilus for some reason.
If you are really that sensitive to yeast toxins, it would be wise for you to avoid any chronic mold exposure, for the rest of your life. Some people lack the ability to properly detox some mycotoxins and thus become incredibly sensitive to them. Symptom presentation includes alot of what you described, particularly the neuro symptoms, for those types. The problem typically gets worse with prolonged exposure. Also, some people with lyme/coinfections will become sensitive to mycotoxins like that, especially those with the detox problem. Not to scare you, but its something to keep in mind if it becomes an issue for you.
