I am sorry to hear about your struggle with candida. I am sure fast heart beat is not fun. Do you have mercury dental fillings by any chance? If you do more likely you have to much mercury in your blood which leads to having candida. The book Candida30: Permanently Heal Your Candida Infection in 30 Days or Less helped me to get rid of my candida. The book is full of great advices on how to clean a body from mercury, what anti fungals to take and what diet to follow. I hope this information helps and you get better soon!
