I have been feeling lightheaded and weak for about a yr now. I have been to every doctor and all the tests are normal. I am a 43 yr old male and I am driving my wife crazy with this issue. I see many people talk about Candida and I thought maybe I have that. The problem is my symptoms are the same for about a 100 different issues. I wanted to know if there is anyway of really knowing if I have Candida. I did this spit test but I am wondering if that was just to sell a product or for real. Also what product can I take to get rid of this? I am depressed because I feel like such crap and I really need to find a solution. Please provide me with some info and a way to fix this.
