Does anyone feel "toxic"

Hi all - I am pretty sure that I have intestinal yeast and also Leaky Gut Syndrome. I am starting treatment with Dr. Biamonte this weekend and taking some tests to see where I am at. I was wondering if anyone with bad yeast and intestinal problems feel as if they are "toxic". That is the only way I can describe it. It is like there is something really yucky in my system that just wants to some out. I feel nauseous, sweaty, really tired and spaced out, and just not right, plus I have been having night sweats. I am only 30, so I don't think that it is hormonal. It just feels like I have been poisoned or something, and this has been going on for over 3 years. Does anyone else feel like this? Thanks.
