I'm going to try this at home, using my mum as a donor. She is healthy but will do some routine tests to I'm living with chronic insomnia (can only sleep with prescription meds), chronic depression and anxiety, abdominal pain, loss of taste/smell, fullness after eating some foods, chronic brain fog, white tongue, drugged/drunk feeling, mind racing, ringing in ears, heart racing, etc. Most of this started when I was using Candibactin AR last September and have gradually deteriorated since. I had depression/anxiety/some insomnia before this but everything became much worse after using the antimicrobial. At the time I was taking it with probiotics for several months without any major issues (except it gave me constipation), then I stopped using the probiotics for a week or so and that's when the anxiety/depression/insomnia all became much worse. I would stop taking the supplement and restart it a week or two later and find most of my symptoms would go away but it would only last a few days before things deteriorated again. I've tried antibiotics with some relief from the insomnia but I relapsed a few weeks ago while going through a stressful event. I can't take any probiotics, they all make my insomnia worse, or give some other intolerable side effect. I struggle to take any other supplements (for methylation or whatever), I feel constantly wired that it doesn't take much to add to that.
